Abstract: 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).

Abstract: Molding materials containing high molecular weight polyphenylene ethers are produced by a process in which a solution of a polyphenylene ether in an organic solvent, together with another polymer, is freed of solvent by multi-stage evaporation. The solvent is preferably an aromatic compound from the class comprising the hydrocarbons, halohydrocarbons, ethers or esters, the ratio of the other polymer to the polyphenylene ether is advantageously from 99:1 to 20:80 parts by weight, the other polymer is, in particular, a homopolymer or copolymer of styrene or of a homolog thereof, which may be modified with rubber, and the multi-stage evaporation process preferably comprises not less than two and not more than four working up stages. The evaporation is carried out in general at from 120 DEG to 280 DEG C. and under a pressure of from 1 to 3,000 mbar, advantageously in the presence of assistants which reduce the partial pressure, eg. water and/or methanol.

Abstract: The invention relates to a moulding composition containing a hard matrix A of polystyrene in a proportion of from 70 to 95 % by weight, based on the moulding composition of A+B, and a soft phase B, distributed therein, in a proportion of from 30 to 35 % by weight, based on the moulding composition of A+B, which has a mean particle size in the range of from 0.1 to 1.5 mu m (number average). The soft phase is a graft copolymer of styrene on an elastomeric monovinylaromatic-butadiene two-block copolymer. The monovinylaromatic monomer for building up the two-block copolymer comprises ring-alkylated methyl styrenes such that the soft phase B contains more than 70% (number average) of shell particles.

Abstract: The invention relates to a flameproofed thermoplastic moulding compound containing a thermoplastic resin A and, in each case based on 100 parts by weight of the resin A, if appropriate an elastomer B, 5 to 50 parts by weight of at least one halogen-containing organic compound C (flame retardant) and, if appropriate, up to 20 parts by weight of a metal-containing or non-metal-containing compound (synergist) D. The flame retardant (C) used comprises brominated triarylamines of the general formula (I) where aryl represents a phenyl, naphthyl, anthracenyl, phenanthrenyl, fluorenyl or fluoranthenyl, biphenyl, triphenylenyl or acenaphthenylene radical and the radicals can be substituted if appropriate with alkyl, alkoxy or aryloxy, and where, furthermore, m, n and p represent integers with the proviso that m = 1-5, and n and p can be the same or different and can each have values from 0-5. The moulding compounds according to the invention are used for producing mouldings.
