Kind Code:
B2
Abstract:
1. Thermoplastic moulding compositions consisting of : A) 25-50 parts by weight of a vinyl chloride homo- or copolymer, B) 25-50 parts by weight of an ABS polymer produced by graft polymerisation of 1) 30-95 parts by weight of a monomer mixture of styrene, methyl methacrylate, alpha-methylstyrene, either individually or in admixture, on the one hand, and acrylonitrile, on the other hand, in a ratio of 90:10 to 60:40 on to 2) 70-5 parts by weight of a butadiene homo- or copolymer, 3) the resulting grafted rubber having an average particle size of 0.05-5 mu m, C) 0-10 parts by weight of a resin-like, thermoplastic copolymer of a styrene/acrylonitrile or methyl methacrylate/acrylonitrile copolymer which has a Staudinger index [eta] of >= 3 dl/g and the [eta] value of which is in any case higher than that of the copolymer contained in the basic polymer B), D) 5-40 parts by weight of an ethylene/vinyl acetate copolymer with a content of vinyl acetate of >= 50 % by weight or of an ethylene/C1 -C10 acrylic ester copolymer or of an ethylene/vinyl acetate/carbon monoxide terpolymer with a content of vinyl acetate of >= 20 % by weight, the polymers having average molecular weights of > 1 500, E) 3-30 parts by weight of a butadiene/acrylonitrile copolymer rubber component which has an acrylonitrile content of 10-35 % by weight and a gel content of >= 60 %, and F) 0-15 parts by weight of a polyester polyurethane based on aliphatic polymers and polyisocyanates with a molecular weight of >= 600, it being possible for the vinyl chloride polymers forming component A optionally to be grafted on to polymers D, E or F as the graft base.
