THERMOPLASTIC MOLDING MATERIALS Abstract of the Disclosure Thermoplastic molding materials contain a copolymer A and a graft copolymer B. The copolymer A is a hard com- ponent comprising one or more copolymers of styrene and/or .alpha.-methylstyrene with from 20 to 40 percent by weight of acrylonitrile. The graft copolymer B comprises a crosslinked acrylate polymer with a mean particle size of 0.5-0.8 um (d50 value of the cumulative mass distribution), a particle distribution, expressed by the ratio Q = Image in the range Q ? 0.6, and a glass transition temperature Tg below 0°C. A mixture of styrene and acrylonitrile in a weight ratio from 88:12 to 65:35 is grafted onto this rubber.
