Flory认为经典凝胶化理论和实际反应体系的偏差主要应归因于分子内环化。本文用概率论的基本原理,统计分析了三类含有双动力学参数的缩聚体系反应到一定程度时,对应于某一基团的各偶数代官能团的消长情况。在此基础上通过引入成环键几率因子,获得了这些体系的解析形式的内环化方程。用本文得到的理论方程处理临界凝胶化条件,理论值和实验值符合得很好。
Flory believes that the deviation between classical gel theory and the actual reaction system is mainly due to intramolecular cyclization. In this paper, we use the basic principle of probability theory to statistically analyze the growth and decline of the even-numbered functional groups corresponding to a certain group when the three kinds of polycondensation systems containing double-kinetic parameters react to a certain extent. Based on this, the analytic form of the inner cyclization equations for these systems are obtained by introducing the probability of ring-forming bond. Using the theoretical equation obtained in this paper to deal with critical gelation conditions, the theoretical and experimental values are in good agreement.
