Abstract: The catalyst is removed in the preparation of high molecular weight polyphenylene ethers from monohydric phenols, which are alkyl-substituted at the two ortho-positions but not at the para-position and may or may not be alkyl-substituted at the meta-position, by an oxidative coupling reaction with oxygen at from 15 DEG to 50 DEG C. in the presence of a catalyst complex obtained from a copper salt and an organic amine, in the presence of from 1 to 20 parts by weight of a solvent per part by weight of the monomeric phenol, and in the presence or absence of an activator, and removal of the metal component of the catalyst from the polyphenylene ether solution with a complex-forming or chelate-forming compound in aqueous solution, in the presence or absence of reducing and stabilizing substances and assistants for accelerating the interphase reactions and for phase separation, by a method in which the continuous removal of the copper catalyst is carried out in one or more mixer-settler stages at a phase volume ratio of the organic phase to the aqueous phase of from 1:0.1 to 1:1.0, preferably from 1:0.4 to 1:0.6.

Abstract: The invention relates to a process for the removal of the catalyst in the preparation of high-molecular-weight polyphenylene ethers from monohydric phenols by oxidative coupling reaction with oxygen at temperatures between 15 and 50 DEG C in the presence of a catalyst complex comprising a metal salt and an organic amine in the presence of a solvent, and removal of the metal ion component of the catalyst from the polyphenylene ether solution by means of complexing or chelate complexing compounds in aqueous medium, the complexing and removal of the metal ion component of the catalyst being carried out in the presence of from 0.1 to 5000 mg/kg of high-molecular-weight, at least partially water-soluble polymers of (meth)acrylic acid and/or of (meth)acrylamide.
