The cure and thermal degradation kinetics of diglycidyl ether of bisphenol A (DGEBA)/4,4'-methylene dianiline (MDA)/phenyl glycidyl eithe. (PGE)-acetamide (AcAm)/carboxyl terminated butadiene acrylonitrile copolymer (CTBN) system were studied by Kissinger equation. The activation energy of the cure reaction is 11.15 kcal/mol and the pre-exponential factor is 16.31 × 10⁵ min^-1. Reaction orders are varied from 1.42 to 1.68 depending on cure temperatures. The activation energy of the thermal degradation reaction is 34.89 kcal/mol and the pre-exponential factor is 2.04 × 10 min^-1. The reaction orders were ranged from 4.83 to 5.85 according to the decomposition temperatures. The theoretical and experimental kinetics are well fitted, and it implies that Kissinger equation is applicable for studying the cure and thermal degradation kinetics.
