The thiol-epoxy click reaction has been employed in the curing of diglycidyl ether of bisphenol A (DGEBA) using latent amine precursors in ratios of 0.5 and 2 phr. The kinetics of the curing of mixtures of DGEBA/thiol/amine precursor was studied by calorimetry under isothermal and non-isothermal conditions. The latent characteristics of the formulations containing amine precursors were investigated by rheometry and calorimetry. The thermal stability of the thermosets and their thermomechanical characteristics were evaluated by thermogravimetry and dynamomechanical analysis. The new formulations were compared with those containing benzyl dimethyl amine or 1-methylimidazole as catalysts. The use of amine precursors in these systems extended the pot-life of the formulations and permitted a better control of the curing process. (C) 2014 Elsevier Ltd. All rights reserved.
