Thermoplastic molding materials comprise A) from 30 to 98% by weight of a graft polymer of aK) from 30 to 90% by weight of an elastomeric graft core, obtainable by copolymerization of aK/1) from 80 to 99.99% by weight of a C1-C10-alkyl ester of acrylic acid, aK/2) from 0.01 to 20% by weight of a crosslinking monomer and aK/3) from 0 to 40% by weight of one or more further monomers, and aS) from 10 to 70% by weight of a graft shell of aS/1) from 50 to 100% by weight of a styrene compound of the general formula <IMAGE> where R1 and R2 are each hydrogen or C1-C8-alkyl, and/or of a C1-C8-alkyl ester of acrylic acid or methacrylic acid, and aS/2) from 0 to 50% by weight of one or more further monomers, B) from 1 to 50% by weight of a thermoplastic polymer of b1) from 50 to 100% by weight of styrene and/or alpha -methylstyrene, b2) from 0 to 50% by weight of acrylonitrile and b3) from 0 to 50% by weight of one or more further monomers, and C) from 1 to 70% by weight of a copolymer of c1) from 30 to 90% by weight of styrene and/or alpha -methylstyrene, C2) from 10 to 70% by weight of butadiene and C3) from 0 to 30% by weight of one or more further monomers, in which all or virtually all of the olefinic double bonds have been hydrogenated.
