| Abstract: | The curing reactions of the epoxy resin triglycidyl-p-aminophenol with acid anhydrides using tertiary amine as catalyst were studied kinetically by differential scanning calorimetry. The dynamic scans in the temperature range 30–300°C were analyzed to estimate the activation energy and the order of the reaction for the curing process using some empirical relations. The curing process was found to follow a simple Arrhenius type kinetics having activation energies in the range 75 – 142 kJ/mol and the order of the reaction is about 1. The effect of the variation in acid anhydride structure and of the incorporation of the epoxy fortifier on the cure characteristics is investigated. |
