NOVOLAC RESIN, CURING AGENT CONTAINING SAME, AND EPOXY RESIN COMPOSITION, AND NOVOLAC EPOXY RESIN, PREPARATION METHOD THEREFOR, AND EPOXY RESIN COMPOSITION CONTAINING NOVOLAC EPOXY RESIN

WIPO Patent Application WO/2015/076626

A1

The present invention relates to a novolac resin, a curing agent containing the same, and an epoxy resin composition, and more specifically, to: a novolac resin of which the degree of polymerization and the molecular weight are controlled to be in specific ranges in order to remarkably improve high thermal stability at a high temperature and moisture resistance while having low viscosity; a novolac curing agent containing the same; and an epoxy resin composition. In addition, the present invention relates to a novolac epoxy resin, a preparation method therefor, and an epoxy resin composition containing the novolac epoxy resin, and more specifically, provides: a novolac epoxy resin of which the degree of polymerization and the molecular weight are controlled to be in specific ranges in order to remarkably improve high thermal stability at a high temperature and moisture resistance while having low viscosity; a preparation method therefor; and an epoxy resin composition containing the novolac epoxy resin.
