Abstract
The influence of the amounts of dicyandiamide curing agent and benzyl- N, N-dimethylamine accelerator on the curing kinetics of a non-brominated epoxy resin and those of epoxy resins containing 20% and 46% bromine was studied by differential scanning calorimetry (DSC). The temperature of the maximal reaction rate (peak temperature), the heat of reaction, the activation energy, and the reaction order were measured or calculated. It was found that the peak temperature decreases with increasing amounts of curing agent and accelerator, but increases with an increasing amount of bromine in the resin. The heat of reaction and the activation energy also increase with increasing amount of bromine.
