| Abstract: | The study of the cure reaction of the epoxy
network diglycidyl ether of bisphenol A with amantidine is a useful tool to
characterize the industrial behaviour of this material. The total enthalpy
of reaction, the glass transition temperature and the partial enthalpies at
different cured temperatures have been determined using differential scanning
calorimetry in dynamic and isothermal mode. Two models, one based on chemical
kinetics and the other accounting for diffusion were used and compared with
experimental data. It can be seen that the inclusion of a diffusion factor
in the kinetic model is negligible. |
