Abstract
A process for preparing phenol oxidation products, and in particular high molecular weight polyarylene ethers, by contacting phenols with oxygen in the presence of a copper compound and a nitrogen compound, characterized in that said process, as a compound of copper, use is made of a compound in which copper presents a stage of oxidation lower than in the case of cuprous compounds.
