| titleOfInvention | Process for producing polyphenylene ether |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a linear polyphenylene ether which can be imparted with high heat resistance by introduction into a polyester resin, an epoxy resin, etc., has a reactive hydroxyl group, has a narrow molecular weight distribution, and is linear. thing. SOLUTION: An alkali metal salt (a1) of 4,4′-dihydroxydiphenyl ether and 4,4′-dihalogenated diphenyl ether (a2) are reacted in an organic solvent (Y) in the presence of a transition metal catalyst (X). A process for producing polyphenylene ether, characterized in that [Selection figure] None |
