【 摘 要 】

The kinetics of the curing reaction of cyanate resin modified by ESi was studied using DSC. The apparent activition energy, reaction order and frequency factor of the curing reaction of the resin were obtained as being E=68.58kJ mol-1, A=2992.06 s-1, n=0.89 respectively. In addition, the gel point, setting point, post cure temperature of this resin was found to be at 149.40°C, 180.72°C, 238.98°C.
