摘要: 丁基锂和二异丙烯基苯的加成物为引发剂的双官能团活性聚合反应是合成遥爪聚合物的主要途径.本文基于离子型聚合反应的非稳态动力学理论,建立了由反应的初始条件和单体转化率计算这类遥爪聚合物的分子量分布和其他分子参数的方法,并举例进行数值计算,给出了各种分子参数随单体转化率变化的规律.

Abstract: Telechelic polymers are synthesized via bi-functional living polymerization Initiated mainly by the adduct of sec-butyl lithium and m-diisopropenylbenzene. On the basis of the nonsteady state theory of kinetics of anionic polymerization, a method is established, with which the molecular weight distribution and other molecular parameters of the resultant polymer can be calculated from the reaction condition. Several examples of numerical computation are given, the data tabulated and the curves drawn illustrat the relationship between the molecular parameters and monomer conversion.
