Definitions
- Nitrile-containing cure site monomers may also be used.
- anionic stabilization is provided by anionic endgroups , mostly -COOH- and -0S0 3 H- groups, and by the adsorbed anionic emulsifier such as PFOA.
- anionic endgroups mostly -COOH- and -0S0 3 H- groups
- anionic emulsifier such as PFOA.
- Such anionically stabilized dispersions tend to coagulate readily in an anion exchange bed and thus jam the ion exchange bed. Therefore, the treatment of an anionically stabilized dispersion with an anion exchanger is considered to be technically not feasible, in particular at higher concentrations.
- the cationic and anionic exchange processes are similar.
- the polymer latex is ion exchanged by passing the dispersion through a column packed with the desired exchange resin (dimension of the column: diameter 6 cm, height 30 cm) .
- the latex can be delivered to the column by any means typical for a chromatographic procedure, e.g. gravity feed, static siphon or an automatic pumping system.
- the particular method used to pass the dispersion through the column is not critical.
- the elution rate should not exceed 3 times the bed volume/hour.
- the dispersion after anionic exchange from Example 1 was treated in a similar manner with 400 ml of the cationic exchange resin.
- the exchanged dispersion had a pH of 3.
- the polymer was isolated from the dispersion by freeze coagulation.
- the polymer resin was analyzed by ICP as described above.
- the cation contents are listed in Table 2 and are compared to the polymer obtained via freeze coagulation from a not ion exchanged dispersion and, additionally, compared with a polymer obtained by MgCl - coagulation to demonstrate the advantage of ion-free coagulation methods.
- the pressurized latex was fed to a nozzle (from the homogenizer as described in US-A-5 463 021) and there expanded to normal pressure.
- the resulting coagulate was washed and dewatered in a filterpress.
- the aqueous filtrate contained 0.5% of solids.
- Example 5 Example 4 was repeated with carbon dioxide instead of nitrogen and pressurized at 40 °C to 100 bar.
- the aqueous filtrate contained 0.3 % of solids.
- Examples 6 to 10 These samples demonstrate the purity of peroxide cured samples for different compositions with respect to the elastomer and the use of partially crystalline fluoropolymer fillers.
- the materials were purified according to the inventive procedure as described in Examples 1 and 2.
- the resins were recovered by freeze coagulation (Examples 6, 7 and 10) or mechanical coagulation (Examples 8 and 9) .
- Table 4 identifies the used formulations for the curing with and without organo-onium compounds and the curing performance.
- Table 5 lists some extraction datas of the cured materials and shows a very low content of extractible ions.
- compositions contain 100 parts of elastomer, "125 parts” means 100 parts of elastomer + 25 parts of filler, (a) means compositions without and (b) with onium salt Onl or 0n2.
- Onl triphenylbenzyl phosphonium/chloride (neat) .
- On2 is Triphenylbenzyl phosphonium/chloride (neat) /methanol 50% solution
- Table 5 Extraction data in ng/g of cured samples in ultra-pure water. Leaching volume: 250 ml, sample weight: 10 g cut-outs of sheets of 2 mm thickness, leaching time: 14 days at 85 °C , , o, , e, , , n, n, 4 are e ow detection limits.
- Compression set 20.4% Extraction studies in ultra-pure water at 85 °C after 14 days (sample weight: 2 g, leaching volume: 500 ml) resulted in a content of 50 ⁇ g/L ammonium and 15 ⁇ g/L fluoride. Al, Cu, Mg, Zn, Fe, Ni, Ca, K, sulfate, chloride are below detection limit.
