ABSTRACT:
Thermoplastic moulding compositions of
1. 70 - 20 % by weight of graft polycarbonates whose graft stock is a vinyl polymer with a molecular weight of from 10,000 to 100,000, containing from 3 to 10 side chains attached by carbon, each of which contains a hydroxyphenyl group, on which aromatic polycarbonate chains are condensed, and
2. 30 - 80 % by weight of graft polymer rubbers obtained by polymerizing a mixture of
2.1. 50 - 90 % by weight styrene, .alpha.-methylstyrene, methylmethacrylate or mixtures thereof, and
2.2. 10 - 50 % by weight acrylonitrile, methacrylonitrile, methylmethacrylate or mixtures thereof on a diene or acrylate rubber.
