Description

Conventional phenolic resins based on either a resole or a novolac with hexamethylenetetramine is usually cured through condensation reaction, evolving several volatiles while curing. Cure with evolution of volatiles necessitates the application of pressure during molding to get void-free molded articles. But recently, there have been investigated new type phenolic resins cured through addition reactions.<BR>In this article, certain kinds of addiotion-curable phenolic resins are reviewed. The intermediates from these phenolic resin have such functuinal groups as allyl, maleimide, acetylene, nitrile, as well as benzoxiazine ring. These phenolic resins cured through addition resections are superior in heat and flame resistance, and toughness, to those of phenolic resins cured with hexamethylenetetramine. These addition-curable phenolic resins are also suggested to be useful as matrix resins for fiber reinforced plastics.
