摘要: Thermoplastic moulding compositions of(A) 20 to 99 parts by weight of a vinyl chloride homopolymer or copolymer containing at least 80% by weight of vinyl chloride and having K-values of from 50 to 80,(B) 80 to 1 part by weight of a graft polymer produced by the solution polymerization in an organic solvent of(a) styrene and/or methyl methacrylate or(b) styrene and acrylonitrile and, optionally, methyl methacrylatein the presence of an EPDM rubber.
