An impact-resistant thermoplastic molding material which contains, based in each case on A+B, from 80 to 50% by weight of a hard matrix A of polystyrene having a molecular weight M.eta. of from 150,000 to 200,000 and from 50 to 20% by weight of a soft phase B which is uniformly distributed in the hard matrix and has a median particle diameter d.sub.50 (volume average) of from 1 to 10 .mu.m, and can be obtained by polymerizing styrene in the presence of an elastomeric grafting base, advantageously has a molecular weight of the grafted branches of from 1.1 to 1.35 times the molecular weight of the hard matrix, and the degree of grafting is from 50 to 100%.
