Abstract

Abstract: O-Cresol novolac epoxy resins (ECN) were cured with phenol novolac resin (NOV) and three esterified phenol novolac resins.Gravimetric method and DMAwere used to study the effect of water absorption on the dynamic relaxation.Experimental results show that the relaxation behavior is greatly affected by the water absorption, which is affected by the polarity and the flexibility of the side groups.

Key words: Phenol novolac resin, Epoxy resins, Water absorption, Dynamic relaxation
