•The dependencies of the activation energy versus degree of epoxy conversion are analyzed.•A new coefficient value is proposed to tabulate the plot of Flynn–Wall and Ozawa.•Different iso-conversional plots of several reactions are commented in comparison.
Applying the differential scanning calorimetry, DSC, we discuss in this study the so called iso-conversional kinetics, ICK, of different epoxy–amine reactions. Single point model free methods, such as the method of Kissinger for the peak maximum temperature evolution in programmed temperature DSC regime, are applied in comparison. The dependencies of the activation energy versus degree of epoxy conversion are analyzed for the systems studied from the point of view of the probable reaction models. Important features and limitations of the ICK approach are also commented.
