Abstract: Thermoplastic moulding compositions containing: from 55 to 85% by weight of a copolymer A composed of styrene and acrylonitrile, from 10 to 40% by weight of at least one graft copolymer B composed of B1: from 50 to 80% by weight, preferably from 60 to 70% by weight, of crosslinked acrylate polymer B1 with average particle diameter from 300 to 700 nm as graft base B1, B2: a first graft shell B2 made of from 5 to 30 of a vinylaromatic monomer B21, and B3: a second graft shell B3 made of from 15 to 40 of a mixture of vinylaromatic monomers B31 and nitrile monomers B32, where these are present in a ratio by weight of from 4:1 to 3:2, and from 0 to 5% by weight of additives and/or auxiliaries C, have particular mechanical properties when the content of acrylonitrile in the copolymer component A and the content of acrylonitrile in the graft shell B3 differ by at least 8% by weight.
