An impact resistance thermoplastic molding composition contains, each percentage being based on A+B, from 80 to 55% by weight of a hard matrix A of a copolymer containing at least 95% by weight of an aromatic vinyl monomer a11 of from 8 to 10 carbon atoms and at least one comonomer a12 in a proportion of 0.1 to 5% by weight, based on A, and from 45 to 20% by weight of a soft phase B which, uniformly dispersed in the hard matrix, has an average particle diameter d50 (volume average) of from 3.5 to 9 mu m and is obtainable by polymerization of the mixture of monomers a11 and a12 in the presence of an elastomer (rubber) and subsequent isolation of the useful product, wherein the comonomer a12 has the general formula I <IMAGE> (I) where X is -OR2, -COOR2 or -CONHR3, R1 is hydrogen or methyl and R2 and R3 are each alkyl of from 1 or 2 to 10 carbon atoms with at least one OH or epoxy group or at least one other polar group.
