Several kinetic models for unsaturated polyester cure reaction and some existing parameter estimation techniques of these models were introduced.Correlated kinetic parameters and kinetic equations of the autocatalytic empirical kinetic model of LPSMC system were determined by using isothermal DSC to scan the system which was thickened by crystalline polymer(PEG-MAH).Through using a serial curing degree of the system to validate the model,the experimental results were basically identical with the predictions of the autocatalytic empirical kinetic model.This model could provide a theoretical reference to the determination of molding techniques of low pressure SMC.
