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 mono-mer 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 a5/2) from 50 to 100 % by weight of a styrene compound of the general formula where R1 and R2 are each hydrogen or C1-C8-alkyl, and/or of a C1-C8-alkyl ester of acrylic acid or me-thacrylic 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.-methylsty-rene, 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.-methylsty-rene, 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. |
