摘要： 用唐敖庆等曾得到的含内环化Aa-Bb型缩聚反应的固化理论,对配料比为1.3的己二酸-三羟甲基丙烷缩聚反应实验数据进行了分析,得到的溶胶-凝胶分配曲线与实验结果符合的较好,进一步讨论了内环化对凝胶点的影响,算出了凝胶点以上数均、重均和Z均分子量的理论曲线.

关键词: 溶胶-凝胶分配, 缩聚几率, 内环化反应程度, 数均、重均和Z-均分子量

Abstract: By means of the theory of polycondensation reaction of Aa-Bbtype involving intra-molecular cyclization proposed by Tang Au-chin et al, the poiycondensation reaction of hexanedioic acid-trimethylol propane with stoichiometric ratio 1. 3 is analyzed. The theoretical sol-gel distribution curve is in accordance with the experimental results. Furthermore, the contribution of intramolecular cyclization to the gel point is estimated. For post-gel, the number-, weight-and Z-average molecular weights are evaluated.

Key words: Sol-gel distribution, Poly condensation probability, Intramolecular cyclization conversion, Number-, weight-and Z-average molecular weights
