Abstract
The curing of an epoxide-amine system in the presence of various amoun ts of dibutyl phthalate as a plasticizer was studied by calorimetry. T he initial rate and the activation energy of the process decrease dram atically, and the highest curing rate passes through a maximum at smal l amounts of the plasticizer added. These effects are explained by the formation of complexes (including the polymeric ones) between the car bonyl groups of the plasticizer and different proton-donating groups o ccurring in this polycondensation system.
