Abstract: A thermoplastic moulding composition containing, based on components A, B and C, A: from 10 to 85 % by weight of at least one polycarbonate A, B: from 10 to 50 % by weight of a graft copolymer B comprising, in each case based on B, b1) from 20 to 80 % by weight of at least one rubber having a glass transition temperature of in which R is hydrogen or a methyl radical and X is a cyclohexyl, methylcyclohexyl, benzyl or phenyl radical, and C: from 5 to 50 % by weight of a thermoplastic polymer of a C1-C4-alkyl ester of methacrylic acid (C1-C4-alkyl methacrylate).

Abstract: Table cutlery, made from a composition containing a high-performance thermoplastic (A), is claimed. Also claimed are: (i) a process for the production of plastic cutlery with a pattern, in which cutlery as above is irradiated with high-energy radiation; and (ii) patterned cutlery obtained by this process. Preferably cutlery is in the form of chopsticks. Plastic (A) comprises polyarylene ether, polyamide, polyester, polymethacrylate, polysiloxane, polyimide, polyether-imide, or copolymers, block copolymers or mixtures thereof.

Abstract: A process for the continuous preparation of high-impact styrene-acrylonitrile polymer (ABS) by free radical-initiated polymerisation of monomeric styrene and acrylonitrile or equivalents thereof in the presence of preformed, dissolved polybutadiene as the graft base, where the solvent used is, in particular, ethylbenzene and, for at least part of the time, the monomers, and phase inversion occurring when a certain process stage has been reached, in two or more reaction zones, the first reaction zone being present at least twice and in each case being in the form of a stirred reactor, so that a stirred reactor is operated batchwise and alternately with the other in such a manner that the reaction mixture polymerises before phase inversion is complete or before the initiator has been consumed, and the respective reactor contents are then fed continuously to a second reaction zone in the form of a tubular reactor.

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.
