从作者提出的统计/动力学建模思想出发，建立了基链在溶胶/凝胶间分配模型，进而建立了溶胶分子平均聚合度模型．仿真计算表明：凝胶分中基链链长明显大于溶胶分；凝胶点过后，溶胶分子量急剧下降，随后根据竞聚率的不同，有不同的变化趋势．模型应用于氯乙烯／邻苯二甲酸二烯丙基酯悬浮交联聚合体系，可较好地预测溶胶分子量随聚合过程的变化．
Based on the idea of statistical / kinetic modeling proposed by the author, a model of the distribution of the base chains between sols and gels was established, and a model of the average sol degree of sol molecules was established. The simulation results show that the chain length of the mid-chain of the gel is obviously larger than that of the sol. After the gel point, the molecular weight of the sol decreases sharply, and then has different trends according to the reheat rate. The model was applied to the suspension polymerization of vinyl chloride / diallyl phthalate, which could predict the molecular weight of sol with the change of polymerization process.
