摘要
从氯乙烯（ＶＣ）两相聚合的特点出发，根据拟动力学常数法和分子量分布矩理论，建立了ＶＣ－微量二烯类单体悬浮共聚物凝胶点前的分子量模型，求得悬挂双键表现活性。结果表明：模型可很好地描述反应过程中分子量变化，悬挂双键表现活性下降一个数量级，物理效应对交联反应有较大的影响。
From the two-phase polymerization of vinyl chloride, a model of DP before gel point inthe vinyl chloride-divinyl monomer suspension polymerization was developed with pseudo-ki-netic constant method and molecular weight distribution moment theory. The parameter k wasobtained from fitting the model with experimental DP. It was concluded that the apparent re-activity of pendent double bonds is reduced by one order and that the physical effect oncrosslinking reaction is quite significant.
