Description
Summary:In this article, a study of the curing process of carboxyl-terminated polyester-triglycidyl isocyanurate systems is reported. A comparison is made between the generally used differential scanning calorimetric methods and rheokinetic methods, which make use of a parallel plate stress rheometer. The curing kinetics was characterized by a regression equation. The crosslinking process can be considered as a phase transformation. The phase transformation was characterized by the Avrami equation and by the scaling parameters. The glass transition temperature conversion dependence was also studied.
