Abstract

Process for the preparation of non-adhesive vinyl chloride polymerizates, by polymerization of vinyl chloride in aqueous suspension or in emulsion, in the presence of mixed polymers of one or more acrylic acid esters, polymerization catalysts, auxiliary suspension or emulsion, as well as optionally in the presence of additives known per se, characterized in that the polymerization of the vinyl chloride is carried out in the presence of 0.5 to 1.5% of passage, preferably 0.8 to 1.3% by weight (calculated as solid matter and referred to the monomer used in vinyl chloride) of mixed polymers of one or more acrylic acid esters with alcohols up to C4 with acrylonitrile and/or acrylamide with a mixed polymer of acrylic acid esters, which have the relative viscosity below 1.1 and by emulsion polymerization at temperatures between 80-125ºC preferably 90-115ºC or had been obtained by polymerization n of solution in the absence of slippery media and in the presence of an organic solvent, liquid at room temperature, at temperatures of 90ºC-140ºC, preferably 95ºC-120ºC.
