Abstract: Moulded compositions comprising a matrix of impact-modified polystyrene and rubber included in the form of discrete particles contain at least 50% by weight of polystyrene A and an effective amount of up to 50% by weight of a graft rubber B. The graft rubber B comprises from 40 to 95% by weight of a rubber-elastic graft core b1 and from 5 to 60% by weight of a graft shell b2, namely from 5 to 50% by weight of a first graft shell b21 comprising styrene and from 50 to 95% by weight of a second graft shell b22 comprising from 60 to 90% by weight of styrene and from 10 to 40% by weight of acrylonitrile, the amounts of A and B, b1 and b2, b21 and b22 and styrene and acrylonitrile in each case adding up to 100% by weight.
