Abstract

The kinetics of the curing process of isocyanate-epoxy materials hardened in the presence of 1- substituted imidazole derivatives was studied by the Coast-Redfern method. The extent of a conversion parameter of the curing process in two ways was calculated: DSC (peak area integration) and rheology (viscosity changes). The activation energy values were determined for epoxy-isocyanate cured in the presence of 0.5; 1.0 and 2.0 phr 1-substituted imidazole derivatives respectively. Increasing of accelerators amount results in decreasing the activation energy and other kinetic parameters.
