the initial kinetics of the polymerization from dicyclopentadiene (DCPD) to polydicyclopentadiene(PDCPD) has been studied . The polymerization of DCPD is initiated by molybdenum pentachloride (MoCl5) and diethylaluminun chloride (Et2AlCl). The kinetics data under different conditions are measured by dilatometer. According to the chain mechanism of ring - opening polymerization
initiated by metal - carbene active centers
the intrinsic kinetics equation is derived by poly - parameter nonlinear optimization (Powell program). The activity energy is 32.022 ×103 J·mol-1.
