Title:
EPOXY RESIN COMPOSITION, NOVEL PHENOL RESIN, NOVEL EPOXY RESIN, METHOD FOR PRODUCING PHENOL RESIN, METHOD FOR PRODUCING EPOXY RESIN, AND CURED PRODUCT OF EPOXY RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2006/022251
Kind Code:
A1
Abstract:
Disclosed is a phenol resin whose cured product exhibits high heat resistance even though the phenol resin uses trialkylphenol as the raw material phenol. Also disclosed is an epoxy resin composition containing an epoxy resin which uses such a phenol resin as a raw material. Further disclosed is a method for commercially producing the phenol resin or epoxy resin with high yield by a simple process. Specifically, a novel novolac phenol resin obtained by reacting 2,4,6-trialkylphenol with formalin in the presence of a methanesulfonic acid, or a novel novolac epoxy resin obtained by reacting the novel novolac phenol resin and epichlorohydrin is contained as a base resin or a curing agent.
