    Abstract: The thermoplastic moulding compositions comprise from 20 to 80% by weight of a polycarbonate A; from 10 to 60% by weight of a thermoplastic copolymer B comprising, in each case based on B, from 70 to 90% by weight of styrene, alpha -methylstyrene or a ring-alkylated styrene, and from 10 to 30% by weight of (meth)acrylonitrile; from 5 to 30% by weight of a graft copolymer C comprising, in each case based on C, from 20 to 60% by weight of a polybutadiene rubber c1 from 80 to 40% by weight of a shell c2 grafted thereto and comprising, in each case based on c2, either from 70 to 90% by weight of styrene c21 and from 10 to 30% by weight of (meth)acrylonitrile c22, or of a shell c2 comprising from 15 to 40% by weight of styrene c23, from 85 to 60% by weight of methyl methacrylate c24 and up to 3% by weight of glycidyl methacrylate c25; from 5 to 30% by weight of a graft copolymer D comprising, in each case based on D, from 20 to 60% by weight of a crosslinked acrylate rubber d1, from 80 to 40% by weight of a shell d2 grafted thereto and comprising, in each case based on d2, from 70 to 90% by weight of styrene d21 and from 10 to 30% by weight of (meth)acrylonitrile d22, with the proviso that the graft copolymer C has a mean particle diameter of from 0.2 to 0.5 mu m and the graft copolymer D has a mean particle diameter of from 0.4 to 0.7 mu m, in each case determined as the d50 value of the cumulative weight distribution.
