本文以二元活性共聚物的模型来处理星形高聚物结合点的二乙烯苯凝胶,参考了活性二元共聚物的统计理论,得到了活性预聚物与二乙烯苯的反应产物的分子量与支化度的分布函数。在活性聚苯乙烯、对位二乙烯苯、正丁基锂与苯的反应体系中,进行了实验验证。结果表明:在配料比不大的情况下,理论分析与实验结果基本一致。在上述理论分析基础上,结合实验数据,得到了两个分布参数以及控制支化度及支化度分布的规律。
In this paper, the binary active copolymer model was used to deal with the divinylbenzene gel of the star polymer binding site. The statistical theory of the active binary copolymer was used to obtain the reaction product of the active prepolymer and divinylbenzene Distribution function of molecular weight and degree of branching. In the living polystyrene, p-divinylbenzene, n-butyl lithium and benzene reaction system, the experimental verification. The results show that the theoretical analysis and experimental results are basically the same when the proportion of ingredients is not large. Based on the above theoretical analysis and the experimental data, two distribution parameters as well as the laws governing the distribution of branching degree and branching degree were obtained.
