THERMOPLASTISCHE FORMMASSE

Thermoplastic molding materials contain a copolymer A and a graft copolymer B. The copolymer A is a hard component comprising one or more copolymers of styrene and/or alpha -methylstyrene with from 20 to 40% by weight of acrylonitrile. The graft copolymer B comprises one or more crosslinked acrylate...

Summary:Thermoplastic molding materials contain a copolymer A and a graft copolymer B. The copolymer A is a hard component comprising one or more copolymers of styrene and/or alpha -methylstyrene with from 20 to 40% by weight of acrylonitrile. The graft copolymer B comprises one or more crosslinked acrylate polymer with a mean particle size of 0.5-0.8 mu m (d50 value of the cumulative mass distribution), a particle distribution, expressed by the ratio in the range Q>/=0.6, and a glass transition temperature Tg below 0 DEG C. A mixture of styrene and acrylonitrile in a weight ratio from 88:12 to 65:35 is grafted onto this rubber.
