Epoxy resin composition, prepreg and metal-clad laminate

摘要

An epoxy resin composition of the invention comprises: an epoxy resin; a hardening agent; and a phenol-modified polyphenylene oxide having a number average molecular weight of 1000 to 4000, which is prepared by carried out a redistribution reaction between a polyphenylene oxide and a phenol compound in the presence of a reaction initiator which can be decomposed to generate an alcohol, a prepreg and a metal-clad laminate of the invention contain the epoxy resin composition.
