Thermoplastic moulding masses

Abstract

Abstract 1. A thermoplastic moulding composition consisting essentially of A 10 to 90 parts by weight of at least one polycarbonate, B 10 to 50 parts by weight of at least one graft copolymer obtained by grafting onto b1 40 to 80% by weight, based on (B), of at least one rubber, the glass transition temperature of which is below 0 degree C, b2 20 to 60% by weight, based on (B), of a mixture of styrene and acrylonitrile in a weight ratio of 88:12 to 65:35, C 0.2 to 80 parts by weight of a hard component which may have been prepared separately and consists of at least one copolymer of styrene and/or alpha-methylstyrene with acrylonitrile, the copolymer containing from 20 to 40% by weight of acrylonitrile units, D 0.1 to 5 parts by weight of at least one terpolymer derived from the monomers styrene, acrylic acid and maleic anhydride, the amount of styrene being from 55 to 65, the amount of acrylic acid being from 5 to 20, and the amount of maleic anhydride being from 15 to 40% by weight, the weight percentages being based in each case on the terpolymer, and optionally E conventional additives in effective amounts.
