The curing kinetics of unsaturated polyester resin with benzoyl peroxide was studied within the temperature range of 348-378 ^oK. A modified kinetic expression was devised by introducing cure induction time and maximum degree of cure, and the kinetic parameters were determined using differential scanning calorimetry.
We also carried out both numerical and experimental studies on compression molding processes of the resin system in order to test the proposed kinetic equation. From the results, it was found that the present kinetic expression enabled us to predict the molding process successfully.
