Comparative DSC kinetics of the reaction of DGEBA with aromatic diamines IV. Iso-conversional kinetic analysis

摘要

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. (C) 2014 Elsevier B.V. All rights reserved.
