摘要: 本文在解析两种单体(丁二烯和丙烯)交替配位增长反应的基础上,借助稳态假定,求得了交替配位增长的速率常数kB-P和kP-B,竞聚率和活化能EB-P、EP-B;并用图解法处理实测的聚合速度数据,求得了两种单体的分反应级数,确立了聚合速度方程式。

Abstract: On the basis of analysis of two monomers alternating propagation, the rate constants, i. e. kB-P and kP-B, reactivity ratio and activation energy were determined according to the hypothesis of steady-state. In addition, the partial reaction orders for two monomers were obtained through treating the data of polymerization rate by graphic method.
