A fractional‐life method coupled with dynamic differential scanning calorimetry (DSC) scan was employed to study the kinetics of the isothermal polymerization of the DGEBA (diglycidyl ether bisphenol A)/HHPA (hexahydrophthalic anhydride)/BDMA (benzyl dimethyl amine) resin system. This method avoids the problem of uncertainty in the total heat evolution in the isothermal DSC scan, The reaction orders obtained for this epoxy resin vary from 1.05 to 1.44 in the temperature range 118–135°C and are believed to be more accurate than those determined in previous studies.
