通过严格的动力学方法推导出阴离子型自缩聚开环超支化共聚合体系（SCROCP）的分布函数及各级统计矩数,进而给出了该共聚体系的二维重量分布函数、数均、重均分子量及多分散指数的解析公式。在SCROCP中的研究成果可推广到阴离子型自缩聚开环均聚体系（SCROP）中,此时活化剂的当量少于单体的当量,有一些单体没有被活化剂激活成引发剂单体,反应体系实际上是按共聚的机理进行的。计算结果表明,当初始单体含量较高时,移除残余单体可以使体系的多分散指数大大降低。

The Molecular weight distribution function and its various moments of anionic self-condensing ring-opening hyperbranched copolymerization system(SCROCP) are deduced by kinetic method.The expressions of two-dimensional molecular weight distribution as well as expressions of number-,weight-average molecular weights and polydispersity index are also derived.The approach developed in SCROCP can be applied to the anionic ring-opening polymerization system(SCROP),if the molar concentration of stimulus is less than that of monomers,some monomer molecules could not be stimulated to inimers by the stimulus,so the reaction can be regarded as anionic ring-opening copolymerization.Numerical calculation shows that the polydispersity index decreases greatly by subtraction of the residual monomers if the initial ratio of monomers to inimers is higher.
