Substituted phenol-formaldehyde novolac resins containing reduced quantities of 2-functional components and epoxy novolac resins prepared therefrom

摘要

The 2-functional component of substituted phenol-aldehyde novolac resins is reduced. Epoxy novolac resins prepared from the novolac resin containing reduced quantities of 2-functional product exhibit increased Tg values when cured.
