    Abstract: The invention relates to a thermoplastic moulding composition containing A from 20 to 80% by weight of a thermoplastic polysulphone, B from 10 to 50% by weight of a copolymer based on b1) a vinylaromatic monomer from the group consisting of styrene, alpha -methylstyrene and p-methylstyrene, or mixtures thereof, and b2) acrylonitrile, and C from 10 to 60% by weight of at least one graft copolymer comprising, in each case based on C, c1) from 50 to 90% by weight of at least one elastomer (rubber) and c2) from 10 to 50% by weight of at least one shell grafted onto the elastomer, is characterised in that the copolymer B used contains, based on B, from 88 to 73% by weight of the vinylaromatic monomer b1) and from 12 to 27% by weight of acrylonitrile b2) in copolymerised form, and the viscosity indices are in the range from 50 to 120, and that furthermore, a graft copolymer C having a mean particle size in the range from 80 to 500 nm (d50 value of the cumulative weight distribution) is used whose elastomer c1) contains, in copolymerised form, c11 at least 80% by weight of butadiene and c12 from 0 to 20% by weight of styrene and/or acrylonitrile, and whose shell c2 contains, based thereon, c21 from 90 to 10% by weight of styrene and c22 from 10 to 90% by weight of methyl methacrylate. The moulding composition is used for the production of mouldings.

    Abstract: A thermoplastic molding material consists of a polycarbonate A and a graft copolymer B, the latter consisting of an elastomer (rubber) (b1) and a shell (b2) grafted onto the elastomer. The elastomer (b1) contains, as copolymerized units, from 35 to 100% by weight of a diene from the group consisting of the conjugated dienes of 4 to 5 carbon atoms, and can contain, as copolymerized units, from 0 to 65% by weight of a monomer from the group consisting of the alkyl acrylates or alkyl methacrylates, where alkyl is of 1 to 8 carbon atoms. The shell (b2) is obtained in a conventional manner by successive polymerization of the monomers constituting the shell, in two process steps, in the presence of the elastomer (b1); in a first process step, from 10 to 90% by weight of a mixture of a vinylaromatic hydrocarbon and one or more ethylenically unsaturated monomers which differ from the said hydrocarbon, in a weight ratio of from 90:10 to 60:40, are first incorporated as copolymerized units, followed by the polymerization of from 90 to 10% by weight of a monomer from the group consisting of the alkyl acrylates or of the alkyl methacrylates, where alkyl is of 1 to 8 carbon atoms. The molding material is used for the production of shaped articles.
