    摘要： A thermoplastic molding material consists of a polycarbonate A and a graft copolymer B, the latter consisting of an elastomer (rubber) (b.sub.1) and a shell (b.sub.2) grafted onto the elastomer.The elastomer (b.sub.1) 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 (b.sub.2) 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 (b.sub.1); 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.

    摘要： High molecular weight polyphenylene ethers are prepared from monohydric phenols by an oxidative coupling reaction with oxygen in the presence of a catalyst complex obtained from a copper salt and an organic amine by a method wherein the metal component of the catalyst is separated off, after the polymerization, by the addition of a polymeric polycarboxylic acid which is essentially composed of unsaturated monofunctional or difunctional carboxylic acids and/or their anhydrides.Advantageously, the polymeric polycarboxylic acids used are homopolymers or copolymers of (a) from 50 to 100% by weight of one or more unsaturated monofunctional acids of 3 to 10 carbon atoms and/or one or more difunctional acids or their anhydrides of 4 to 6 carbon atoms and from 0 to 50% by weight of one or more monomers which do not possess an acid function and can be copolymerized with (a).

    摘要： A process for the manufacture of high impact and translucent polystyrene, in which, in a first stage, styrene is prepolymerized in mass or in solution in the presence of a rubber, and the polymerization is then completed in mass, in solution or in aqueous suspension. The prepolymerization is taken to a stage where the amount of styrene converted is from 3 to 10 times the amount of the elastomer constituent of the rubber, and at this conversion the disperse soft-component phase formed should have a mean particle size of less than 1 .mu.m and should contain from 35 to 65% by weight of free or chemically bonded polystyrene segments. The translucent styrene polymers of high impact strength may be used for packaging purposes.
