The curing reaction of an epoxy system consisting of a diglycidyl ether of bisphenol A (BADGE n = 0) and 1,2-diaminocyclohexane (DCH) was studied by Fourier Trasform Infrared Spectroscopy (FTIR). From the infrared spectra using a peak-height method, that was based on the ratio of the height of the characteristic to reference absorbance peak, degree of conversion at different isothermal temperatures were calculated. From a kinetic study, the Horie et al. model was used; parameters such as rate constants and activation energies were determined. The results were compared to those obtained for same epoxy systems using scanning differential calorimetry (DSC).
