ABSTRACT:
A novel process is disclosed for the preparation of polyphenylene ethers by an oxidative coupling reaction. The process comprises oxidatively coupling a phenolic compound in the presence of a catalyst which comprises a copper complex of a copper compound with an N,N.sup.1 -disubstituted alkylene or cycloalkylene diamine having from 2 to 3 carbon atoms between the nitrogen atoms and whose substituents on the two nitrogens atoms are isopropyl or alpha tertiary alkyl, a tertiary amine, a secondary mono-amine and a bromine containing compound.
