Abstract:The non-isothermal curing kinetics of acrolein-pentaerythritol resin system were studied by dynamic differential scanning calorimetry(DSC). The DSC data were analyzed by the Kissinger and Crane equations. The kinetic parameters were calculated and the curing kinetic model for acrolein-pentaerythritol resin system was also established. Based on the viscosity experiments at 341, 347, 353 K and 359 K, the rheological model on the foundation of Arrhenius equation was built. Results show that the apparent activation energy, reaction order and frequency factor of curing reaction are 14.32 kJ·mol-1, 0.95, 3.84×103 K, respectively. The curing degree are 0.9503, 0.9147, 0.8871 and 0.8695 at the heating rates of 10, 15, 20 ℃·min-1and 30 ℃·min-1, which indicates that with the decreasing of heating rate, the curing degree increases.
