Method for preparing hydroxyalkyl-functionalized polyphenylene ether.

摘要

Disclosed is a method for preparing a hydroxyalkyl-functionalized polyphenylene ether which comprises reacting a polyphenylene ether represented by the formula: <CHEM> wherein Q1 each represents a halogen atom, a primary or secondary alkyl group, a phenyl group, an aminoalkyl group, a hydrocarbonoxy group or a halohydrocarbonoxy group; Q2 each represents a hydrogen atom, a halogen atom, a primary or secondary alkyl group, a phenyl group, a haloalkyl group, a hydrocarbonoxy group or a halohydrocarbonoxy group; and m is an integer of 10 or more, with a functionalizing agent in the presence or absence of an organic solvent capable of dissolving the polyphenylene ether and in the presence of a basic catalyst.
