Thermoplastic moulding composition

Abstract

Abstract The moulding composition comprises a rigid component A and two graft copolymers B and C. The rigid component A is present in a proportion of from 50 to 90% by weight and is a copolymer of styrene with acrylonitrile. The graft copolymer B is present in a proportion from 5 to 45% by weight and is formed from 40 to 80% by weight of a crosslinked acrylate polymer having a mean particle size of from 0.02 to 0.15 mu m (d50 value of the integral weight distribution) as a graft base, onto which from 20 to 60% by weight of a mixture of styrene and acrylonitrile is grafted. The graft copolymer C makes up from 5 to 45% by weight and comprises from 50 to 85% by weight of a copolymer formed from 20 to 80% by weight of butyl acrylate and/or ethylhexyl acrylate and from 20 to 80% by weight of butadiene having a mean particle size > 0.20 mu m (d50 value of the integral weight distribution), onto which from 15 to 50% by weight of a mixture of styrene and acrylonitrile is grafted. The moulding composition according to the invention is used to produce mouldings.
