ABSTRACT:
An improved process for producing a polyphenylene ether with low nitrogen content and low odor properties employs, for oxidative coupling of a 2,6-disubstituted phenol, a novel catalyst comprising a copper compound, a diamine, a tertiary amine, a quaternary compound and an unsaturated compound. The new polyphenylene ether is suitable for polymer blending, with, for example, styrenic resins, to make low odor blends.
