Vinylidenchlorid und Acrylnitril als brauchbareThe present invention is based on film-forming ones which are already capable of the adhesive strength and the solutions that contain copolymers of two different hardnesses which are obtained from the solutions of the poly-different components. It is a question of increasing merisate forming films. Firstly, it is colored by a copolymer, which consists of more than the films can be through .. Incorporation of their 50% vinylidene chloride and acrylonitrile; solutions with pigment dyes, such as other copolymers, are made from vinyl acetate and phthalocyanines. To build thick (tall) films to he-maleic acid dibutyl ester. The film that forms from the solutions of the solutions is often made up of the mixed polymerizate compounds of the montmorillonite building blocks of two different, separately prepared or colloidal solutions of the silicon dioxide supplied polymers. One can admit here. Instead of such solutions, according to the Anglo-Saxon usage, it is possible to speak of “blending” by adding the finest silicon dioxide. Such plastics 30 have a certain amount of particles. The thixotropy of the solutions has proven itself. The aim here is to achieve "blending"copolymers; this is reminiscent of polyvinyl chloride with polyethylene. This given the opportunity to apply thick layers. "Blending" creates a "blended".,: _ <. ·; ■ If there is a need to give the resulting plastic with excellent physical properties a certain elasticity, shafts are created that are suitable for many purposes 35 so have chosen the copolymer from which polyvinyl chloride is superior.

In addition, the Solution, based on the two copolymers dissolved in it, 2.5 parts of silicon dioxide pigment with a particle size of 0.2 microns. The silica is in suspension, but it is largely dispersed, so that when the mixture is poured, the silicon dioxide is uniformly distributed is guaranteed in the resulting film. The thickness of the after evaporation of the solvent remaining film can be 50 microns and more. The surface is protected against mineral oil, it can be committed and driven on.
