Summary:PROBLEM TO BE SOLVED: To provide a process of polymerization of a polyphenylene ether which is capable of stably controlling the molecular weight at a desired value. SOLUTION: The process of polymerization of a polyphenylene ether gives a polyphenylene ether with a number average molecular weight of 1,000-20,000 by polymerizing a phenol in the presence of a polymerization medium, a catalyst and a oxygen-containing gas. The content of the phenol in the polymerization medium is 25-60 wt.%. COPYRIGHT: (C)2007,JPO&INPIT
