Description

ACRYLIC LATEX FILMS BASED ON CASTOR OIL (METH) ACRYLATE DERIVATIVES

FIELD OF THE INVENTION

[0001] The present invention relates to compositions comprising reaction products. The reaction products comprise acetoacetoxyethyl (meth)acrylate moieties and castor oil (meth)acrylate moieties.

BACKGROUND OF THE INVENTION

[0002] Traditionally, polymeric compositions that were to be formed into films or other materials were solvent based. The solvent facilitated the film formation and drying of the polymeric compositions so that the polymer could be cured. The trend is to move away from solvent based polymeric compositions to water based polymeric compositions.

[0003] A problem with curing water based polymeric compositions is that, in the absence of solvent, heat is required so that the polymers can cure. The application of heat requires the consumption of energy, which can increase the cost of curing the polymeric composition. In some applications, it is desired for films to cure at ambient temperature. Therefore, it is desirable to find polymers that can be cured by auto-oxidation or even radiation by actinic light.

[0004] Examples of auto-oxidative polymers that have been discovered to date can be found in U.S. Patent No. 6,242,528; U.S. Patent No. 6,235,916; U.S. Patent No. 6,203,720; U.S. Patent No. 6,174,948; U.S. Patent No. 6,001,913; U.S. Patent No. 5,767,199; U.S. Patent No. 5,484,849; U.S. Patent No. 4,906,684; WO 01/44380; and WO 00/56826.

[0005] A composition comprising a polymer, wherein the polymer comprises at least one of: a) a blend of a first polymer comprising a reaction product of acetoacetoxyethyl (meth)acrylate monomer and a second polymer comprising a reaction product of castor oil (meth)acrylate monomer, and b) a third polymer comprising a reaction product of acetoacetoxyethyl (meth)acrylate monomer and castor oil (meth)acrylate monomer. [0006] Additionally, a method comprising: a) applying the composition to a substrate, and b) curing the composition by at least one of auto-oxidation and actinic radiation; wherein when the composition is cured by auto-oxidation, optionally a drier is added to the composition prior to applying, and wherein when the composition is cured by actinic radiation, optionally an actinic radiation curing agent is added to the composition prior to applying.

[0067] When the compositions of the present invention are formed into a film, they can be cured by at least one of auto-oxidation and actinic radiation. Additionally, heat can be used to cure the films.

[0068] A film can be provided by a method comprising: a) applying the composition to a substrate, and b) curing the composition by at least one of auto-oxidation and actinic radiation, wherein when the composition is cured by auto-oxidation, a drier is optionally added to the composition prior to applying, and wherein when the composition is cured by actinic radiation, optionally an actinic radiation curing agent is added to the composition prior to applying. [0069] When the compositions of the present invention are formed into a film and are curable by auto-oxidation, a drier can be added to the compositions to facilitate curing. Driers are materials that promote or accelerate curing or hardening of the polymers when they are applied as a film.

[0070] Examples of driers that can be included in the composition of the present invention include, but are not limited to, neutral soaps of the formula (R_x-COO^~)₂M²⁺ or (R_x-COO^")₃M³⁺; acid soaps of the formula (R_x-COO^")₂M^2+»R_x-COOH or (R_x-COO^~ )₃M³⁺*R_x-COOH; basic soaps of the formula (R_x-COO^")₂M^2+»OH; organic complexed or mixed soaps of the formula (R_x-COO^")(R'_x-COO-)M²⁺ or (R_x-COO^~)(R'_x-COO^~)(R"_x- COO^")M³⁺; inorganic/organic complexed or mixed soaps of the formula O-M²⁺-O-CO-R_x, Y-O-M²⁺-O-CO-R_x, and O-M²⁺-O-CO-R_x; wherein R_x-COO^", R'_x-COO^", and R"_x-COO^" are aliphatic carboxylic acid ions having 6 to 20 carbon atoms, x is an integer from 6 to 20, M = metal ion, and Y = phosphorus or boron. Additionally, driers can be any polyvalent metal containing complex or salt that catalyzes the oxidative curing. Examples are polyvalent metal salts containing cobalt, calcium, manganese, copper, zinc, iron, and zirconium as the cation. Simple salts such as halides, nitrates, and sulfates can be used, but also organic anions, such as acetate, naphthenate, or acetoacetonate, can be used to obtain a more water soluble or water miscible drier.

[0071] The commonly used carboxylic acids for forming the metal driers are aliphatic acids, preferably fatty acids. Examples of fatty acids include rosin oil fatty acid, linseed oil fatty acid, and tall oil fatty acid. Naphthenic acids obtained from certain petroleum crudes may also be used for forming the suitable metal driers. The naphthenic acids generally contains an average of 12-14 carbon atoms having a cyclopentane nucleus with the carboxyl group terminating a side chain and with one to three methylenic groups between the carboxyl and the nucleus. Various other synthetic acids having 8 to 10 carbon atoms are also used to form the metal driers, and include, for example, 2- ethylhexanoic acid and neodecanoic acids.

[0072] Examples of metals that can be used in the driers include, but are not limited to, cobalt, zirconium, manganese, calcium, lead, zinc, copper, barium, vanadium, cerium, iron, potassium, strontium, aluminum, bismuth, and lithium. Particularly prefeπed metal driers are aliphatic carboxylic salts of cobalt, manganese, lead, zirconium, calcium, and mixtures thereof. A detailed description of various metal driers may be found in "Surface Coatings-Raw Materials and Their Usage," Vol. I, Chapman & Hall, Chapter 33, pp 592- 606 (1993), which is incorporated herein by reference, and in U.S. Patent No. 5,559,192, which is incorporated herein by reference.

[0073] Additionally, in combination with a drier, a volatile stabilizer can be included. Examples of volatile stabilizers include, but are not limited to, ketone oximes and hindered aldehyde oxime. Examples of these include, but are not limited to, methyl ethyl ketone oxime, methyl butyl ketone oxime, 5-methyl-3-heptanone oxime, and cyclohexanone oxime. Volatile stabilizers are generally used at 0.05 to 1% by weight of the composition.

[0074] The amount of driers that can be included in the compositions can be any amount that promotes or accelerates curing or hardening of the polymers. Generally, the amount of driers ranges from about 0.01%) to about 1% metal content based on the weight of the composition, and preferably from about 0.05% to about 0.5%.

[0075] When the compositions of the present invention are formed into a film and are curable by actinic radiation, an actinic radiation curing agent can be added to the compositions to facilitate curing. Actinic radiation curing agents are materials that promote or accelerate curing or hardening of the polymers when they are applied as a film and are radiated with actinic radiation. Preferably, the composition does not contain an actinic radiation curing agent. One type of actinic radiation is UV radiation. Any wavelength of actinic radiation that promotes or accelerates the cure of the polymers can be used. Generally, the wavelength of radiation ranges from about 200nm to about 500nm.

[0076] Examples of actinic radiation curing agents include, but are not limited to, benzophenone, 4-methylbenzophenone, benzoyl benzoates, phenylacetophenones, 2,2- dimethoxy-2-phenylacetophenone, and amine modified diacrylates.

[0077] The amount of actinic radiation curing agents that can be included in the compositions can be any amount that promotes or accelerates curing or hardening of the polymers. Generally, the amount of actinic radiation curing agents ranges from about 0% to about 1% based on the weight of the composition, and preferably from about 0% to about 0.5%.

[0078] The combination of acetoacetoxyethyl (meth)acrylate and castor oil (meth)acrylate in a polymer composition can improve the modulus of the polymer when the polymer is formed into a film. The improvement in modulus can be as great as 600% or more.

[0079] Uses of the compositions of the present invention include, but are not limited to, coatings, including original equipment manufacture (OEM) automotive coatings, refmish automotive coatings, architectural coatings, paper coatings, textile coatings, industrial coatings, furniture coatings, powder coatings, graphic arts, inks, adhesives, binders, nonwovens, paper saturation, medical applications (such as dentifrice, sutures, and bandages), and construction chemicals. Polymer crosslinking provides chemical and stain resistance in coatings as well improved processability, toughness, and service life in other applications

Latex synthesis [0081] To achieve auto-oxidative crosslinking in a latex film the ideal strategy is to have a radical forming functionality in the polymer together with functional groups prone to radical addition. Alternatively, these two functional groups could be on different polymers that would have to be blended in order to get crosslinking. Thus, we prepared latexes with only one functionality, but also ones that comprise both functional groups - those that generate radicals, and those that allow addition of radicals. The model latexes were designed in such a way as to have similar total solids content (40%>) and T_g.

[0082] The following functional groups were employed: As radical forming entities CAM was used. As entities prone to radical addition, ethyl acetoacetate (EAA) and ethyl γ- aminocrotonate (EAC) were used. The EAC containing polymer was generated from the EAA polymer by reaction with NH₄OH as described in U.S. Patent No. 5,484,849, which is incorporated herein by reference.

[0083] The following model latexes were prepared (see Table 1 below): No. 1 without functional monomer, No. 2/No. 7 with each 10 mol% AAEM NH₃ (pH 9.5), No. 9 with 19 mol% AAEM/NH₃ (pH 9.5), No. 10 with 6 mol% AAEM/NH₃ (pH 9.5) and No. 3/No. 4/No. 12/No. 13 with each 3 mol% CAM, the difference being that No. 3/No. 13 were reacted at 70°C and No. 4/No. 12 at 50°C. A core-shell latex was synthesized, No. 6, with CAM in the outer (shell) phase. In No. 8 the two functional groups AAEM (11 mol%) and CAM (3 mol%) were combined. The total solids (TS) target was 40%> for all samples.

Film studies

[0099] To study auto-oxidative crosslinking behavior, the model latexes No. 1 - No. 9 prepared were treated with additives, and from these mixtures films were drawn. To facilitate autoxidation, a cobalt drier was added as a catalyst. In the films, both the AAEM and the CAM moieties were present to provide crosslinking. Therefore, either AAEM and CAM containing latexes were blended, or an AAEM-latex was mixed with the CAM monomer, or latex No. 8 was used with both functionalities present. The drier salt was a 6% cobalt octanoate solution in mineral spirits sold under the trade name NUXTRA™ from Huls America. The mixing of the drier salt into the composition was facilitated by the inclusion of other additives TEXANOL™ (coalescent), TRITON™ X- 405 from Rohm and Haas (surfactant), and FOAMASTER™ VL from Cognis, Inc. (defoamer). In a first set of experiments, film forming experiments from U.S. Patent No. 5,484,849, which is incorporated herein by reference, were used. The ratios and types of additives used were similar to those in U.S. Patent No. 5,484,849. However, for the formulations used here, the compositions were modified because the procedures in U.S. Patent No. 5,484,849 did not work with the compositions of the present invention in that the compositions formed two layers. When the thickener, NATRASOL™ 250 hydroxyethyl cellulose thickener from Aqualon (2%> aq. solution), was omitted the problem subsided, and the mixture was homogenous. However, in most cases, a greenish precipitate formed, floating on top of the mixture, but nevertheless the mixture displayed a pink color. This problem was solved by adding TEXANOL™ ester alcohol solvent from Eastman in the mixture. In the examples below, the amount of TEXANOL™ solvent and/or glycol listed is the percentage amount by weight that the solvent was added to the composition.

[0100] Evidence for crosslinking can be found in films derived from formulations 33-37, below. Here various AAEM and CAM containing latexes have been blended, and from these formulations films were cast. Results from films 31-37 are shown below in Table 3. Tensile and water absorption data were tested on thick films (500μm). The coalescents used in each example were: 33-37 4.5% TEXANOL™ solvent and 4.5% propylene glycol, and 31 and 32 9% TEXANOL™ solvent. MEK (methyl ethyl ketone) rub data was obtained from thin films (175μm). The curing time for the thick films was 19 days at room temperature.

[0101] A comparison of 31, 32, 33, and 34 provided the following results. The CAM function on its own appeared to be capable of crosslinking, evidenced by comparisons of tensile strengths of 31 and 33. Data show convincing evidence for even a higher degree of crosslinking in 34, compared to 33 (based on tensile data and water absorption) in the thick films. Thus, the AAEM function reinforces the crosslinking. In fact, of all the films prepared here, Film 34 indicates the most crosslinking according to tensile strength, water absorption, and DMA data (provided below). Comparing 35 with the coπesponding blank 36 also gives evidence for crosslinking, as can be seen from the tensile data. It was remarkable how data from thick films coπesponded with data from the thin films (MEK rubs). Whereas data from 33-36 were very similar, with possibly a slight amount of crosslinking for 35, film 37 proved to be very strong. This stands in contrast to tensile data that showed a reduced amount of crosslinking here. The tensile data, however, coπesponded very well with DMA data that show that films were getting stronger (higher modulus = more crosslinked) in the following order: 33<36<35<37<34 (no data for 32 and 31). Again, 34 proves to be crosslinked most, having the highest modulus, and also for 37 and 35, there was good evidence of crosslinking. A comparison of 34 and 35 tends to show that the "core-shell" CAM latex from Sample No. 6 did not perform as well as the one-stage latex from Sample No. 4 in these experiments. One possible reason might be that the Sample No. 6 was synthesized at a higher temperature than Sample No. 4 (70°C vs. 50°C) possibly causing premature crosslinking. The results from dymanic mechanical analysis (DMA) on the film samples is given in Table 4 below.

[0102] Additional films were prepared as described above and formulated as shown in

Table 5 below. Results for films 41 - 54 are shown in Table 5 below. Tensile and water absorption data were received from thick films, and MEK rub data from thin films

(coalescents used: 41-48 4.5% TEXANOL™ solvent and 4.5% propylene glycol, 49 9% TEXANOL™ solvent, 50-54 4.5% TEXANOL™ solvent). Curing time was 19 days at room temperature.

Ratio of blends was 1 :1, except for 52 and 53. (h) Latex Sample No. 8. (i) AAEM latex and CAM monomer, (j) here, only 0.08 wt% drier was added (usually 0.75%). [0103] In samples 41-48, there was less evidence of crosslinking. Therefore, the "core- shell" CAM latex (Sample No. 6), as well as the combined AAEM/CAM latex (Sample No. 8) do not show as much crosslinking as the CAM latex Sample No. 4. The latter one was the only CAM system synthesized at 50°C, which might be a result of less premature crosslinking. Reviewing films 49-54, clear evidence for crosslinking can be found. In particular, comparing 49 through 51, 50 was the strongest film, the other two being blanks. Exceptionally strong was 53, with a ratio of AAEM latex versus CAM latex 1 :3. Also 54, where CAM monomer was added to the AAEM latex shows crosslinking. DMA data strongly supports this evidence, which is given in Table 6 below. Of samples 49-54, 49 exhibited the lowest modulus, and 51 the second lowest. Both samples were blanks, either without AAEM or without the drier. Moduli of 50, 52, 53 and 54 were significantly higher.

[0104] Additional films 63-69 were prepared as above and formulated as shown in Table 7 below. In examples 63-69, again crosslinking can be shown. The blanks 63 and 64 gave the highest elongation data points by far. Using a latex with higher AAEM content gave better results than using one with a lower content, for example comparing the 30wt% AAEM latex versus the 17wt% AAEM latex. Film 69 produced a reduced tensile strength and low elasticity data. As shown above, at least in part, water absorption and MEK rub data do not necessarily coπespond. Results for films 63-69 are shown below in Table 7. Curing time for thick films was 19 days at room temperature.

From DMA data given in Table 8 below, the strongest cases for crosslinking among the examples were films 67 and 69. Comparing 67 and 68, 68 gave showed less crosslinking (lower modulus). Table 8

[0105] Additional films 73-78 and 84 were prepared as above and formulated as shown in Table 9 below. Film 77 was the same as film 2. Of films 73-76, 76 displayed the highest tensile strength. The model/AAEM blend in film 77 gave a low tensile strength, CAM derived film 78 gave a very high tensile strength and also a very high elasticity (666%> max. elongation). Also, here the water absorption was very low, indicating crosslinking. Films 77 and 78 showed that CAM seemed to be able to induce and reinforce crosslinking, whereas AAEM only reinforces when in combination with CAM. Based on the economic cost of CAM and AAEM, it is desired to substitute as much CAM for AAEM as possible. Results for films 73-78 and 84 are shown below in Table 9. Drying time was 31 days at room temperature.

AAEM(30) contains 30% (T_g -7) AAEM, Sample No. 9. CAM was Sample No. 4.

[0106] Additional films 91 and 92 were prepared as described above and formulated as shown in Table 10 below. As observed for the majority of thin films, MEK rubs provided reduced support for crosslinking. This was only true, however, for films dried on air (ambient conditions). Films 91 and 92 showed that when dried in a humidity chamber (100%) humidity), there was a significant difference in film strength for a sample that contained the drier (Film 91) compaired to one that did not contain it (Film 92). Without being limited by theory, under humid conditions, films would be allowed to dry slower, which may cause efficient polymer diffusion between particles in the process of film formation. This result strongly shows crosslinking during film formation. The results for films 91 and 92 are shown in Table 10 below. The condition in the humidity chamber coπesponded to 100%> humidity. The drying time was 33 days at room temperature. Table 10

[0107] Additional films 93-98 were prepared as described above and formulated as described in Table 11 below. The following set of data showed how film strength decreases with less drier used and also with less AAEM used. AAEM alone results in low tensile strength (Films 97 and 98). Data for films 93-97 are shown below in Table 11. Drying time was 19 days at room temperature.

[0108] Additional films were prepared as described above and formulated as described in Table 12 below. Film samples 120 and 124 - 127 were prepared without CAM. Films 124 - 127 show the influence of the T_g on tensile strength. Drying time was 19 days at room temperature.

[0109] Additional films 128-135 were prepared as described above and formulated as shown in Table 13 below. From formulations 128 - 135 thin films were drawn and tested via MEK rubs. As shown above (Films 91 and 92), there was a difference in result from films dried on air (ambient conditions) as compared to those from films dried in a humidity chamber. Crosslinking was most pronounced in films 128/129, 130/131 and 132/133, that were not reproduced in the air-dried films. Film 130, based on CAM alone, was more resistant against MEK than Film 128, based on AAEM and CAM. Results from MEK rubs on thin films (9%> TEXANOL™ solvent was used in the film formulations) are shown in Table 13 below. The condition in the humidity chamber coπesponds to 100% humidity. The drying time was 26 days at room temperature.

[0110] Additional films 136-141 were prepared as described above and formulated as shown in Table 14 below. The following data suggests that the combined AAEM/CAM latex Sample No. 11 does not provide as much crosslinking when dried on air with the cobalt drier as does the other samples. The low tensile strength of 136 suggests a lower amount crosslinking. Similar results were achieved with Sample No. 8. Sample No. 11 was synthesized at 50°C, and according to proton NMR spectroscopy, it contained impurities. Films 139 - 141 show that there was less crosslinking when bis-acrylate (1,4- butanediol-bisacrylate) or CAM monomer was added to AAEM latex Sample No. 10. This was in contradiction to results described earlier from thin films dried in a humidity chamber. The results for films 136-141 are shown in Table 14 below. Drying time was 21 days at room temperature. In Table 14 below, AAEM/CAM (T_g -33) = Sample No. 11 and AAEM (9, T_g -14) = Sample No. 10.

Table 14

[0111] Summary of CAM/ AAEM crosslinking studies: Evidence for crosslinking in films derived from formulations with combined AAEM (acetoacetoxyethylmethacrylate) and CAM (castor oil acrylate monomer) functions was obtained, particularly through tensile test data and DMA analysis. Effects were already well pronounced after 3 weeks drying time at room temperature. It was shown that blends of latexes that contain AAEM and CAM functions, respectively, work best. Also, an AAEM latex can be mixed with CAM monomer to give crosslinking, and additionally the combined AAEM/CAM latex Sample No. 8 gave positive results.

AAEM/CAM crosslinking through UV cure

[0112] As an alternative to air oxidation, curing with actinic radiation was tested. In these examples, the actinic radiation was UV radiation, which ranged from 200-5 OOnm. To facilitate UV curing, samples were prepared containing a UV curing agent, benzophenone. UV cured films proved to be much stronger than the blank samples that were not UV cured. When comparing films 82 and 83, it can be seen that without the UV curing agent, results were even better. Without being limited to theory, it is theorized that the enamine adjunct of AAEM acts as a photosensitizer itself; whereas, benzophenone might quench photoprocesses or cause bond-breaking. A minor UV crosslinking effect can be seen with CAM alone (84) or even with the model system (86). The temperature in the UV chamber was measured to be 50°C, therefore blank tests were conducted with samples being cured at that temperature. From these blanks it can be stated that the crosslinking in the UV-cured films was due mainly to the UV light, and to a lesser degree, to heat. In films 84 and 86, heat curing gave exceptionally high tensile strengths. Note, the temperature in the UV chamber was not a constant 50°C. It varied ±5°C.

[0113] For comparison puφoses with the auto-oxidation films, some of the formulations in the UV curing examples contained TEXANOL™ solvent. Those samples that contained TEXANOL™ solvent will be indicated below.

[0114] Compositions were prepared as described below in Table 15 and films 81-86 were prepared with a thickness of 500μm. Drying time was initially 11 days without UV curing at room temperature, and then 7 days with UV iπadiation from a xenon lamp. For respective room temperature blanks, drying time was 18 days, and for heat-cured blanks the drying time was 18 days at room temperature and 7 days at 50°C). TEXANOL™ solvent was added to the compositions at 9% by weight. The results are shown in Table 15 below.

(a) UV-sensitizer: 0.3wt% PHOTOMER™ 81 (from Cognis) was used (mixture of benzophenone and 4-methylbenzophenone). (b) Latex blends: "model" denotes a straight acrylics system (BA, MMA), Sample No. 1; "AAEM" and "CAM" (Sample No. 4) denote latexes with these functionalities. AAEM(30) contains 30%> (T_g -7) AAEM, Sample No. 9, and A(T_g-2)(17) contains 17%, Sample No. 7.

[0115] Additional films 102-106 were prepared as described above and formulated as described in Table 16 below. For UV-cured samples, drying time was initially 11 days at room temperature without UV, and then 3 days with UV iπadiation. For respective room temperature blanks, the drying time was 14 days. For heat-cured blanks, drying time was 11 days at room temperature and 3 days at 50°C. TEXANOL™ solvent was added at 4.5%) by weight to the formulations. Results are shown in Table 16 below.

[0116] UV cured samples 102 and 103 displayed much higher tensile strengths compared to room temperature or heat cured samples. Blank film 105 gave weak films; whereas, room temperature and heat cured film 106 was strong, which theoretically may be due to the high T_g (28°C). As described before, the UV sensitizer does not really make a difference, as can be seen from comparison of films 102 and 103.

[0117] Additional films 109-116 were prepared as described above and formulated as described in Table 17 below. For UV-cured samples, drying time was initially 11 days at room temperature without UV, and then 3 days with UV iπadiation. For respective room temperature blanks, drying time was 14 days. For heat-cured blanks, drying time was 11 days at room temperature and 3 days at 50°C. No TEXANOL™ solvent was used in the formulations. Results are shown in Table 17 below.

[0118] As films 109 and 110 show, UV cure did not have any effect on the model system containing only BA and MMA. AAEM alone cures by means of UV iπadiation (films 111 and 112), with the more concentrated system being more efficient (111 and 112, versus 113 and 114). Results of 115 and 116 basically reproduce those of 102 and 103. Results were very similar, even though in 102 and 103 were compounded with TEXANOL™ solvent, whereas 115 and 116 were not.

[0119] Additional films 142-149 were prepared as described above and formulated as described in Table 18 below. To some samples as indicated, CAM monomer (CAM) or 1 ,4-butane-bisacrylate (BA) was added. TEXANOL™ solvent was added to the formulations at 4.5% by weight. Drying time was initially 13 days at room temperature, then 3 days in UV light (UV cure) or oven at 50°C (heat cure). Results are shown in Table 18 below.

[0120] Films 142 and 143 indicated that crosslinking in the combined AAEM CAM latex occuπed when UV cure was provided. Films 144 - 149 showed a reduced effect on crosslinking upon addition of CAM monomer or bisacrylate. Data from AAEM latex blanks, without any additive, showed similar results.

(e) Combined AAEM/CAM latex Sample No. 8, (f) AAEM latex Sample No. 7, T_g -2°C, 17wt% AAEM.

[0121] Additional films 172-173 were prepared as described above and formulated as described in Table 19 below. Films were first allowed to dry for an initial 10 days at room temperature, then they were cured for 2 days either in UV or by heat at 50°C. No TEXANOL™ solvent was used in these formulations. The results are shown in Table 19 below. The data for films 172 and 173 also indicated crosslinking in the AAEM/CAM latex. UV curing shows effects on tensile strength and elongation.

[0122] Additional films 158-165 were prepared as described above and formulated as described in Table 20 below. Films were cured for 3 weeks first at room temperature, and then subjected for a 3 day UV post-cure. CAM latexes, Sample No. 12 and Sample No. 13, showed an increase in tensile strength and elongation when treated with a UV post- cure. Data of Cobalt-dried films of blends with AAEM showed a reduced amount of crosslinking, but upon post-UV curing, tensile data were in accord with crosslinking. Overall, of all CAM latexes prepared, Sample No. 4 worked better in terms of crosslinking in conjunction with AAEM. Without being limited by theory, this was the only CAM latex with 100% conversion in the synthesis, and the other samples most probably contain residual amounts of CAM that act as a plasticizer, resulting in low tensile data.
