PURPOSE:To obtain a polymer having an optional polymerization degree by one- stage reaction at a low cost in very high production yield in a short time, by polymerizing a 2,6-disubstituted phenol in the presence of a specific bisphenol and metal complex catalyst. CONSTITUTION:A 2,6-disubstituted phenol expressed by formula II (R<1> and R<2> are alkyl, alkoxyl or aryl) is polymerized in the presence of a bisphenol expressed by formula I (R<3>-R<6> are H, alkyl or alkoxyl), e.g. 2,2'-bis(3,5-dimethylphenyl)propane, and a metal complex catalyst, e.g. cuprous chloride-copper-pyridine or copper sulfate-triethylamine, to give the aimed polyphenylene oxide expressed by formula III (m and n are as follows; 3<=m+n). The ratio between the compounds expressed by formulas I and II is within 2-100 range, and the polymer having the polymerization degree according to the ratio is obtained. The polymer is useful as a prepolymer for producing polyesters, polycarbonates or epoxy resins.
