چکیده:

The curing reaction of epoxy novolac /tetrabromobisphenol A resin with nadic methyl ahydride as a curing agent and benzyl dimethyl amine as a catalyst was studied by non-isothermal differential scanning calorimetry (DSC) at heating rates of 5, 10, 15 and 20ºC/min. The dynamic scans were analysed to estimate the activation energy and the order of reaction for the curing process using some empirical reactions. The results
were dependent on the catalyst concentration and proceeded through Ozaea and Kissinger equations.
