    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.

    Abstract: A thermoplastic molding material consists of from 10 to 90 parts by weight of a polycarbonate A and from 90 to 10 parts by weight of a graft copolymer B having a mean particle size of from 200 to 700 nm (d50 value of the integral mass distribution). The graft polymer B is formed from an elastomer (rubber) (b1), which accounts for from 10 to 80% by weight, and a grafted shell (b2), which accounts for from 90 to 20% by weight, the percentages in each case being based on (B). The elastomer (b1) is composed of from 50 to 99.9% by weight of an alkyl acrylate, where alkyl is of 1 to 8 carbon atoms, and from 0.1 to 5% by weight of a copolymerizable polyfunctional crosslinking monomer. The grafted shell (b2) is produced in three stages and contains, as graft monomers, (b2a1) from 5 to 40% by weight of a monoethylenically unsaturated aromatic hydrocarbon of not more than 12 carbon atoms, in the first stage, (b2a2) from 15 to 50% by weight of a mixture of a monoethylenically unsaturated aromatic hydrocarbon of not more than 12 carbon atoms and a copolymerizable ethylenically unsaturated monomer, in a weight ratio of from 90:10 to 60:40, in the second stage, and (b2a3) from 10 to 85% by weight of an alkyl (meth)acrylate in the third stage, the percentages in each case being based on (b2).

    Abstract: The invention relates to a thermoplastic moulding composition containing A) from 50 to 98% by weight of a polysulphone resin (polyarylene-polyether-polysulphone), B) from 2 to 50% by weight of a graft copolymer comprising, in each case based on B, b1) from 50 to 90% by weight of at least one elastomer (rubber) and b2) from 10 to 50% by weight of at least one shell grafted onto the elastomer, is characterised in that the graft copolymer B has a mean particle size in the range from 80 to 500 nm (d50 value of the cumulative weight distribution) whose elastomer b1) contains, in copolymerised form, b11 at least 80% by weight of butadiene and b12 from 0 to 20% by weight of styrene and/or acrylonitrile, and whose shell b2 contains, based thereon, b21 from 90 to 10% by weight of styrene and b22 from 10 to 90% by weight of methyl methacrylate. The moulding composition is used for the production of mouldings.
