Abstract: The invention relates to a moulding composition containing a hard matrix A of polystyrene in a proportion of from 70 to 95 % by weight, based on the moulding composition of A+B, and a soft phase B, distributed therein, in a proportion of from 30 to 35 % by weight, based on the moulding composition of A+B, which has a mean particle size in the range of from 0.1 to 1.5 mu m (number average). The soft phase is a graft copolymer of styrene on an elastomeric monovinylaromatic-butadiene two-block copolymer. The monovinylaromatic monomer for building up the two-block copolymer comprises ring-alkylated methyl styrenes such that the soft phase B contains more than 70% (number average) of shell particles.
