Claims
- 1. A thermoplastic molding composition containing:
- A. 52 to 94% by weight of a component consisting of 50 to 100% by weight of a mixture of one or more polycarbonates and 0-50% by weight of a thermoplastic copolymer (C) composed of
- C.1 50 to 95 parts by weight of styrene, .alpha.-methyl styrene, nucleus-substituted styrene, methyl methacrylate or mixtures thereof, and
- C.2 50 to 5 parts by weight (meth)acrylo-nitrile, methyl methacrylate, maleic anhydride, N-substituted maleic imide, or mixtures thereof, the sum of the parts by weight of C.1 and C.2 amounting to 100,
- B. 6 to 48% by weight of one or more particulate graft polymers wherein the graft polymers are prepared by graft polymering
- B.1 20 to 90 parts by weight of a polymer graft overlay of at least one .alpha., .beta.-unsaturated monomer to form an overlay onto
- B.2 80 to 10 parts by weight of a graft base having a core/shell structure, consisting of a core of
- (a) an organic, resin-like polymer of at least one olefinically unsaturated monomer having a glass temperature (Tg) of >30.degree. C. and a shell polymer of
- (b) cross-linked silicone rubber, the ratio of the core (a) to the shell (b) being from 0.1:99.9 to 90:10, the graft polymer (B) having an average particle diameter of from 0.05 to 10 microns and the sum of the parts by weight of B.1 and B.2 amounting to 100.
- 2. A molding composition as claimed in claim 1 wherein the amount of weight of (C) in (A) is not more than one third of the percent by weight of (A) in the composition.
