The curing reaction of a system consisting of a purified diglycidyl ether of bisphenol‐A (BADGE, n = 0) and 1,2 diamine cyclohexane (DCH) was studied with a differential scanning calorimeter. The objective of this article was twofold: a kinetic study from which parameters such as reaction orders, rate constants, and activation energies were determined; and a thermodynamic study where values of enthalpy (ΔH^#), entropy (ΔS^#), and Gibbs free energy (ΔG^#) changes were calculated. This second study showed that an n‐order path reaction mechanism was more favored than the autocatalyzed mechanism above 338 K. This fact was also checked when plotting rate constant ratio against temperature. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 63: 635–641, 1997
