【Abstract】 The thermal physical properties(glass transition temperature T g and specific heat p) of epoxy terminated poly(phenylene ether ketone) and bisphenol A epoxy resin were studied using a differential scanning calorimeter. At the same time, T g and C p were also predicted based on the group contribution method. The prediction results of T g for both fresh sample of epoxy resin and cure agent and fully cured sample are not satisfactory. Therefore, the contribution of the end group in epoxy resin and the cure agent was introduced in the prediction process and the group contribution method was modified.更多还原
