    Abstract: The invention relates to an impact resistant, stress cracking- resistant thermoplastic moulding composition comprising, in each case based on A + B, 80 to 55% by weight of a resin matrix comprising a copolymer A of at least one vinylaromatic monomer a11 having 8 to 10 C atoms and at least one comonomer a12, and 45 to 20% by weight of a soft phase B which is uniformly distributed in the hard matrix and has a mean particle diameter d50 (volume average) of from 3.5 to 9 mu m, as obtained by polymerising a mixture of monomers a11 and a12 in the presence of an elastomer with subsequent isolation of the useful product, comonomer a12 being from 0.05 to 5% by weight based on the sum of A and B, of a vinyl-substituted heterocyclic compound with at least one N atom which does not carry a vinyl group.
