    Abstract: A thermoplastic molding material which contains two graft copolymers in a matrix of a copolymer based on styrene and acrylonitrile. The first graft copolymer (B) comprising a hard phase prepared from one or more vinyl-aromatic monomers and an elastomer phase, the elastomer phase particles having a diameter of from 0.5 to 5 mu m. The second graft copolymer (C) comprising a hard phase and an elastomer phase, said elastomer phase having a bimodal particle distribution in which the diameter of one category of particles is from 0.05 to 0.18 mu m and the second category of particles has a mean diameter of from 0.25 to 0.6 mu m.
