| 摘 要： | 用唐敖庆等曾得到的含内环化A_a-B_b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. |

| Abstract: | By means of the theory of polycondensation reaction of Aa-Bb type 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. |
| Keywords: | Sol-gel distribution Poly condensation probability Intramolecular cyclization conversion Number- weight- and Z-average molecular weights |
