Abstract: A process for the preparation of high molecular weight polyphenylene ethers from alkyl-substituted monohydric phenols by an oxidative coupling reaction with oxygen in the presence of a catalyst complex of a copper salt and an organic amine, subsequent stopping of the reaction and removal of the metal component of the catalyst by addition of chelating and/or salt-forming agents, wherein the polymer solution is treated with a compound having the general structure: where R2 and R3 can be identical or different and each is OH, NH2, NHR5, where R5 is alkyl or cycloalkyl, or SH, and where R1 and R4 are identical or different, being hydrogen, alkyl, cycloalkyl, aryl, carbonyl, carboxyl, carboxyalkyl or nitrile, and can be linked to form a ring, advantageously in an amount of from 0.1 to 100 mmoles and advantageously in from 1 to 20% strength aqueous solutions.

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: The invention relates to a polypropylene-based bumper system comprising a bumper support A (1) comprising glass fibre-reinforced polypropylene, an energy-absorbing foam core B (2) comprising foamed polypropylene, and a tough shell C (3) which comprises EP rubber-modified polypropylene and may, if desired, be painted. The bumper system can be recycled by mechanical comminution, extrusion and granulation. The granules can be used to produce injection mouldings having good mechanical properties.
