Abstract: A polymer mixture comprises (a) 50 to 70% by weight of an emulsion homopolymer or copolymer of vinyl chloride having a K value of 58 to 72; (b) 10 to 30% of a suspension polymer of vinyl chloride having a K value of 50 to 65; and (c) 0.5 to 40% of a graft copolymer of vinyl chloride which has been prepared by the emulsion polymerization technique and in which the vinyl chloride is grafted on a cross-linked copolymer of a conjugated diene and acrylonitrile or methacrylonitrile having a gel content of more than 90%, the graft copolymer being insoluble in organic solvents; the percentages being calculated on the total weight of the mixture. The mixture may also contain (d) 1 to 10% of a cross-linked elastomeric copolymer prepared by emulsion polymerization of a conjugated diene and acrylonitrile or methacrylonitrile, said copolymer being insoluble in organic solvents and having a gel content of more than 80%. Other possible ingredients of the mixture are a stabilizer comprising (i) diphenyl thiourea or alpha-phenyl indole, epoxidized natural oils and an alkalizing water-soluble salt or (ii) an epoxy compound, an organo tin compound, a heavy metal salt of a fatty acid or a mixture of aminocrotonic acid esters of fatty alcohols; and a wax, fatty acid ester or polyolefin as lubricating agent. In the example, the mixture comprises (a) an emulsion polymerized vinyl chloride homopolymer, (b) a suspension polymerized vinyl chloride homopolymer, (c) a graft polymer of vinyl chloride on a cross-linked butadiene-acrylonitrile copolymer, (d) a butadiene-acrylonitrile elastomer, diphenyl thiourea, di-n-octyl tin-bis-thiogly-collic acid octyl ester, epoxidized soybean oil and montan wax.
