Description

USE OF PROPYLENE COPOLYMER WAXES FOR PRODUCTION OF TACKY PLASTICS FILMS
The invention relates to the use of propylene copolymer waxes for production of plastics films with a tacky surface (use as tackifiers).
There is a wide variety of applications needing plastics films with a tacky surface. By way of example, plastics films with a tacky surface are used as silage films in agriculture or as protective films for, by way of example, motor vehicle glazing and motor vehicle body work. There are other requirements placed upon these films alongside tack, an example being that they are to generate little noise on unwinding from wound rolls of film (usually designated as film bobins) (wound film), another intention is that this is feasible without blocking (the term used being "blocking performance").
Specific additives, also termed "tackifiers", are used to achieve the tacky surfaces. The intention is to maximize toxicological and environmental safety of these additives.
Furthermore, the films with a tack surface have to meet the requirements usually placed upon films, examples being ultimate tensile strength, tensile strain at break or transparency.
Page 97 of "Kunststofffolien (Herstellen-EigenschaftenAnwendungen)" [Plastics films (Production-Properties- Applications)] by Nentwig, Hanser Verlag describes the use of certain additives for production of films with tacky surfaces. Examples of materials used are polyisobutylene (PIB), flexible polyvinyl chloride (flexible PVC) and ethylene- vinyl acetate copolymers (EVA copolymers).
There has been a need for films with a tacky surface which meet modern requirements.
Surprisingly, it has been found that the use of certain copolymer waxes during film production leads to tacky surfaces. The invention provides the use of propylene copolymer waxes as tackifiers for production of plastics films with a tacky surface composed of polymers, where the polymers have been selected from the group of polyolefins (PO), preferably polyethylenes (PE) and polypropylenes (PP) and their copolymers, and also ethylene- vinyl acetates (EVA) and styrenics and their copolymers, and also polyamides (PA), polyesters, preferably polyethylene terephthalates (PET) and polybutylene terephthalates (PBT), and also polybutenes (PB), and their copolymers and a mixture composed of these polymers.
Particularly preferred polymers are PE and PP and their copolymers, and also EVA and PET; in particular polyolefins, specifically PE and PP and their copolymers. In the case of PE, it is preferable to use low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE).
The propylene copolymer waxes preferably have from 0.1 to 50% by weight, particularly preferably from 5 to 40 % by weight, in particular from 10 to 30 % by weight, specifically from 12.5 to 25 % by weight, especially from 14 to 22 % by weight, comonomer content, the % by weight based in each case on the total weight of the propylene copolymer wax. Comonomers are preferably 1-alkenes, in particular ethylene. It is also possible to use a plurality of comonomers.
The propylene copolymer waxes preferably have a molecular weight distribution with an average molecular weight Mn (number average) of from 500 to 20 000, particularly preferably from 800 to 10 000, in particular from 1000 to 8000.
Appropriate methods for preparation of olefin homo- and copolymer waxes are described by way of example in Ullmann's Encyclopedia of Industrial Chemistry, 5th edn., Vol. A 28, Weinheim 1996, in Chapter 6.1.1./6.1.2. (high-pressure polymerization), Chapter 6.1.2. (Ziegler-Natta polymerization, polymerization using metallocene catalysts).
It is preferable to use propylene copolymer waxes which have been prepared by means of metallocene catalysts. These waxes have a low drop point, high transparency and low viscosity. Ethylene and/or higher 1 -olefins can be polymerized with the aid of metallocene catalysts (organometallic catalysts) to give unbranched or branched waxes.
The waxes prepared in the presence of metallocene as catalyst are propylene copolymer waxes (hereinafter also termed metallocene polyolefm waxes) composed of propylene and from 0.1 to 50% by weight of ethylene and/or from 0.1 to 50% by weight of at least one branched or unbranched 1-alkene having from 4 to 20 carbon atoms, with the preferred ranges of amounts stated above, with a drop point or softening point (ring/ball) up to 1500C, preferably from 10 to 1500C, particularly preferably from 15 to 1400C, and with a melt viscosity of from 30 to 7000 mPas, preferably from 40 to 4500 mPas, measured at a temperature of 1700C.
The waxes prepared in the presence of metallocene as catalyst are substantially or completely amorphous and can also have polar modification if needed.
Metallocene compounds of the formula I are used for preparation of the inventively used metallocene polyolefin waxes.

Suitable cocatalysts are used to activate the single-centre catalyst systems. Suitable cocatalysts for metallocenes of the formula I are organo aluminium compounds, in particular aluminoxanes, or else aluminium- free systems, such as R20 xNH4-xBR214, R20 xPH4-xBR214, R20 3CBR214 or BR21 3. x in these formulae is a number from 1 to 4, and the radicals R20 are identical or different, preferably identical, and are Ci-Cio-alkyl or C6-Ci8-aryl, or two radicals R20 form a ring together with the atom connecting them, and the radicals R21 are identical or different, preferably identical, and are Cό-Cis-aryl, which may have substitution by alkyl, by haloalkyl, or by fluorine. In particular, R20 is ethyl, propyl, butyl, or phenyl, and R21 is phenyl, pentafluorophenyl, 3,5-bistrifluoro- methylphenyl, mesityl, xylyl, or tolyl.
A third component is also often required in order to maintain protection from polar catalyst poisons. Organoaluminium compounds are suitable for this purpose, examples being triethylaluminium, tributylaluminium, and others, and also mixtures.
As a function of the process, it is also possible to use supported single-centre catalysts. Preference is given to catalyst systems in which the residual contents of support material and cocatalyst do not exceed a concentration of 100 ppm in the product.
The melt viscosities here were determined to DIN 53019 by using a rotation viscometer. Drop point is determined by using an Ubbelohde drop point device to DIN 51801/2, and ring/ball softening point is determined to DIN EN 1427.
The polymers from which the plastics films are produced can be used in solid or molten form, preferably solid and particularly preferably in the form of pellets or in the form of powders.
The propylene copolymer waxes can be used directly or as concentrates, termed masterbatch. The propylene copolymer waxes or their masterbatches are used in solid or liquid form, for example in molten form, preferably in solid form. In solid form, they are preferably used in the form of pellets or in the form of powders.
For production of the plastics films with a tacky surface composed of the polymers, the propylene copolymer waxes are mixed with the polymer. This mixture is processed to give films, preferably via extrusion, in particular via flat-film extrusion (cast films being the term used) and blown- film extrusion. Addition of the propylene copolymer waxes or of a masterbatch to the polymer takes place prior to or during processing of the polymer to give the film, preferably prior to or during the extrusion procedure via direct addition of the propylene copolymer wax to the polymer melt. It is preferable to use from 1 to 20 % by weight, particularly preferably from 2 to 10 % by weight, in particular from 3 to 8 % by weight, of the propylene copolymer wax, the % by weight in each case based on the weight of the polymer from which the plasties film is produced.
The propylene copolymer waxes are preferably used for production of a plasties film whose thickness is from 2 to 400 μm, preferably from 8 to 300 μm, in particular from 10 to 200 μm, with a tacky surface.
The precise amount of the propylene copolymer wax used depends on the desired tack of the film and on the thickness of the film and can be selected appropriately by the person skilled in the art.
The films can also comprise further additives, e.g. light stabilizers, preferably of hindered amine light stabilizer (HALS) type, pigments or antioxidants.
The extent of tack of the film surface, and the time between production of the plastics film and achievement of the desired tack, can be influenced via storage of the plastics films at temperatures of from 200C to 700C, preferably from 200C to 500C, in particular from 20° to 40°, for a period of from 1 to 20 days, preferably from 1 to 15 days, in particular from 1 to 10 days, after production.
Addition of propylene copolymer waxes to polymers, preferably to PP and PE, during production of films gave a tacky, adherent film surface. Use of propylene copolymer waxes results in good performance with respect to blocking of the wound films, i.e. blocking is minimized, this being a requirement for problem-free unwinding of the wound films.
There is little unwinding noise produced during unwinding of the film web from the wound films.
The further requirements mentioned above and usually placed upon films, e.g. ultimate tensile strength, tensile strain at break or transparency, are met.
Since the propylene copolymer waxes are toxicologically and environmentally relatively safe, the films produced using propylene copolymer waxes are also toxicologically and environmentally safer than flexible PVC films which usually comprise plasticizers about which there are toxicological and environmental concerns.
The tacky films produced using propylene copolymer waxes are preferably used in agriculture, for example for the wrapping of hay bales or for silage applications. Another preferred application sector is their use as protective films for glazing, preferably in automobile construction. They are moreover preferably used for protection of painted surfaces, for example in automobile construction.
Examples
The viscosity of the propylene copolymer waxes (tackifiers) was determined to DIN 53019.
The viscosity of the PIB tackifiers (Glissopal® products from BASF) was determined to DIN 51562.
Enthalpy of melting was determined to DIN EN ISO 11357-1. Ethylene content was determined by infrared spectroscopy. Melt flow index (MFI) was determined to DIN 53753.
The propylene copolymer waxes whose data have been listed in table A were added as tackifiers in powder form to an LDPE (LDPE with MFI of 2.0 g/ 10 min). After intimate mixing, the mixture was processed in a laboratory extruder to give pellets. The pellets were used to produce a film of thickness 30 μm on a blown-film plant. The resultant wound films were then unwound and performance during unwinding was evaluated. The factors evaluated were noise level and blocking performance during unwinding of the film rolls. Since these parameters are difficult to measure, an empirical scale from 1 to 3 was selected.
Noise level: 1= low noise level
2= moderate noise level 3= high noise level
Blocking performance: 1= no blocking 2= little blocking 3= marked blocking.
The following propylene copolymer waxes were used:
