    摘要: An improved method for the production of polyphenylene ethers is disclosed. The method comprises oxidatively coupling monohydric phenols in the presence of a complex catalyst and in a liquid medium which is a solvent for the monomer and catalyst and a non-solvent for the polyphenylene ether. The polyphenylene ether precipitates to form a slurry of particulate solids which is then washed with an aqueous solution of a chelating agent to remove catalyst residue.
