ABSTRACT OF THE DISCLOSURE A process is described for oxidative polymeriza- tion of a monomeric 2,6-disubstituted phenol in the pre- sence of a catalyst comprising a manganese compound, an N-alkylalkanolamine and a basic compound. The process produces a polyphenyleneether which does not exhibit deterioration in molecular weight and undesirable colora- tion when subject to heat, such as the heat ordinarily applied in molding. The polyethyleneether have excellent tensile strength and elongation.
