Thermoplastic moulding compositions

Abstract

Abstract Thermoplastic moulding composition containing, based on components A, B and C, A: 10 to 85 % by weight of at least one polycarbonate A, B: 10 to 50 % by weight of a graft copolymer B comprising, in each case based on B, b1: 20 to 80 % by weight of at least one rubber b2 having a glass transition temperature of below 0 DEG C, and b2: 80 to 20 % by weight of a shell b2, grafted onto b1, comprising, in each case based on b2, b21: 70 to 95 % by weight of methyl methacrylate b21 and b22: 5 to 25 % by weight of an N-substituted (meth)acrylamide b22 of the general formula I <IMAGE> in which R is hydrogen or a methyl radical and X is a cyclohexyl, methylcyclohexyl, benzyl or phenyl radical, and C: 5 to 50 % by weight of a thermoplastic polymer or copolymer C of a C1-C4-alkyl methacrylate.
