摘要

THERMOPLASTIC MOULDING COMPOSITIONS OF TRIAZINE CONTAINING POLYCONDENSATES AND GRAFT POLYMERS Thermoplastic moulding compositions of(A) 15 to 80 % by weight of an aromatic polycondensate containing s- triazine rings, and(B) 20 to 85 % by weight of a graft polymer obtained by polymerising a mixture of(B.1) 50 to 90 % by weight of styrene, .alpha.-methyl styrene, methyl methacrylate or mixtures thereof and(B.2) 10 to 50 % by weight of acrylonitrile methacrylo nitrile, methyl methacrylate or mixtures thereof, onto a diene or acrylate rubber, the mixture as a whole containing from 5 to 25 % by weight of s-triazine rings, based on (A) and (B),and 5 to 40% by weight of rubber,based on(A)and(B).
