Synthesis of toughner for epoxy resin and application in adhesive

LI Qi-li

Abstract

In order to empolder toughner for epoxy resins, a series of novel epoxy-terminated polyols(oligomer) was synthesized,Their bonding properties were evaluated in modified epoxy networks by the oligomer. The testing result showed that the shear strength and the peel strength in modified epoxy resin by the oligomer have increased by 59.8% and 108% as compared with unmodified epoxy resin.
