Abstract

The temperature-modulated differential scanning calorimetry (TMDSC) responses during cure of both epoxy/aromatic amine and dicyanate ester/polycyanurate systems are modeled using chemical reaction kinetics with diffusion control. Physical aging effects are incorporated into the model using the Tool-Narayanaswamy-Moynihan (TNM) equation. We investigate the assumption that the mobility factor, which may be obtained from experimental temperature-modulated differential scanning calorimetry reversing heat flow data, is related to the diffusion factor for the two systems.
