Cure kinetics of diglycidyl ether of bisphenol A (DGEBA)/4,4'-methylene dianiline (MDA) systems with three nitriles were investigated by DSC analysis. Nitriles as reactive additives were malononitrile(MN), succinonitrile (SN) and glutaronitrile (GN). To estimate the kinetic parameters, Kissinger equation (dynamic run) and Fractional-life equation (isothermal run) were employed. The activation energy of DGEBA/MDA system is 11.11 kcal/mol and those of the DGEBA/MDA systems with MN, SN and GN are 11.38 kcal/mol, 11.48 kcal/mol and 11.32 kcal/mol, respectively. Due to the disturbance of nitrile compound to the reaction of amine and epoxide group, the activation energy is considered to increase while the cure rate is decreased.
