Abstract: The invention relates to a process for the removal of the metal component of the catalyst from a polyphenylene ether solution produced in the preparation of high-molecular-weight polyphenylene ethers from monohydric phenols by oxidative coupling reaction with oxygen in the presence of a catalyst complex comprising a metal salt and an organic amine in the presence of a solvent and optionally an activator, by treatment with a precipitant which is a solid chemical reagent which is insoluble in the polyphenylene ether solution, and has been applied to an inert support substance which is adsorbent with respect to the precipitated substances. The precipitant is an organic P-, S-, O- or N-containing compound or an inorganic P or S compound which is soluble in water or aqueous acid solution, the support substance is a solid material of any desired shape with a specific surface area of from 50 to 1500 m /g and a porosity of between 50 and 75% which is insoluble in water, acid and organic solvents.

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.
