Abstract
Curing kinetics of glycidyl ether of cresol formaldehyde novolac or novel phosphorus-containing epoxy cured with diaminodiphenyl sulfone (DDS) were studied by the dynamic differential scanning calorimetry (DSC) and isothermal DSC method. Parameters of dynamic curing kinetic were calculated by using the Kissinger and Ozawa's methods, respectively. Parameters including k1, k2, m and n of isothermal curing kinetics were determined by an autocatalytic mechanism proposed by Kamal. The model gave a good description of curing kinetics up to the onset of vitrification. The effect of the diffusion control was described by an approach based on simple equations proposed by Chern and Poehlein. The relations concerning the activation energy of curing and structure of epoxy resins were discussed.
