Abstract

Plastisols of 80 to 5% by weight plasticizer and 20 to 95% by weight particulate polymer containing PA0 (a) from 5 to 60% by weight acrylonitrile, methacrylonitrile or mixture thereof PA0 (b) from 15 to 95% by weight styrene, .alpha.-methyl styrene or mixture thereof PA0 (c) from 0 to 10% by weight of a carboxylic acid copolymerizable with the monomers (a) and (b), PA0 (d) from 0 to 30% by weight and, in the absence of component (c), from 10 to 30% by weight of an alkylester of acrylic acid, methacrylic acid or mixtures thereof optionally a diluent and other constituents, the percentages by weight of plasticizer and polymer being based on the sum of plasticizer and polymer and a process for making such plastisols.
