Modified polyphenylene ether

摘要

Disclosed is a modified polyphenylene ether having a number average molecular weight of not smaller than 4,000, which is obtained by reacting a precursory modified polyphenylene ether with a phenolic compound in the presence of a radical generator, wherein the precursory modified polyphenylene ether comprises a plurality of polyphenylene ether chains each having a terminal phenolic hydroxyl group, wherein the plurality of polyphenylene ether chains collectively have at least one terminal phenolic hydroxyl group modified and wherein not all of the terminal phenolic hydroxyl groups of the plurality of polyphenylene ether chains are modified. Also disclosed is a method for producing the modified polyphenylene ether.
