Process for polymerization of 2,6-disubstituted phenol |
摘要 |
A process is described for oxidative polymerization of a monomeric 2,6-disubstituted phenol in the presence 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 coloration when subject to heat, such as the heat ordinarily applied in molding. The polyethyleneether have excellent tensile strength and elongation.
