Abstract

Epoxy resin of 1,3-bis(4-hydroxyphenyl)prop-2-en-1-one has been synthesized and studied its cure kinetics by differential scanning calorimetry at four different heating rates in nitrogen atmosphere and varying proportions of 4,4′-diaminodiphenyl ether, 4,4′-diaminodiphenyl sulfone and phthalic anhydride. The energy of activation (Ea) and pre-exponential factor (A) has been determined according to Flyn-Wall-Ozawa method at various degrees of cure ranging from 0.1 to 0.9. The derived results are discussed in light of effect of hardeners concentrations, heating rates, degree of cure, and nature of hardeners, etc. The structure of the hardeners and their concentrations affected the cure behavior. © 2013 Wiley Periodicals, Inc.
