Abstract

The investigation of cure kinetics of biphenyl-type epoxy (4,4-diglycidyloxy-3,3, 5,5-tetramethyl biphenyl)/phenol novolac resin system with triphenylphosphine catalyst was performed by differential scanning calorimeter using an isothermal approach. The cure reaction of the system could be explained by considering the formation of epoxy-phenol-catalyst trimolecular active complex and effectively described by combining autocatalytic and nth order model. To describe the cure reaction in the latter stage, a diffusion factor has been used. By combining the proposed kinetic model with a diffusion factor, it is possible to predict the cure kinetics over the whole range of conversion.
