    摘要: 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.degree. to 280.degree. 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.

    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).
