Abstract
A thermoplastic molding material contains 50-90% by weight of a hard component A comprising one or more copolymers of styrene and/or .alpha.-methylstyrene with acrylonitrile, and 50-10% by weight of a graft copolymer B comprising 40-80% by weight of a crosslinked acrylate polymer which has a mean particle size greater than 0.8 .mu.m (d.sub.50 value of the cumulative mass distribution) and onto which 20-60% by weight of a mixture of styrene and acrylonitrile in a weight ratio of from 88:12 to 65:35 is grafted. The novel molding material is used for the production of moldings.
