A thermoplastic molding material which contains, in each case based on the molding material comprising A+B, A. from 50 to 95% by weight of a rigid matrix composed of, (a1) styrene and (a2) acrylonitrile, B. from 50 to 5% by weight of a nonrigid phase which is uniformly dispersed in the rigid matrix and which comprises a graft copolymer of the monomers (a1) and (a2) and a styrene-butadiene block copolymer, wherein the styrene-butadiene block copolymer has a styrene content of from 50 to 95% by weight and a butadiene content of from 50 to 5% by weight, each based on the block polymer, and has a molecular weight (weight average) within the range from 50,000 to 300,000, is used for producing moldings.
