| 摘 要： | Flory、Gordon和唐敖庆从相同的基本假定出发,用不同的几率方法提出了凝胶化理论,统称为经典的凝胶化理论,对A_a-B_b(B′)_b体系,汤心颐等曾研究过其凝胶化范围,但只得到了临界反应程度,我们用经典的统计方法,以甘油和丁二酸酐为模型化合物,研究了溶胶分数与反应程度的关系,并导出了酸/醇摩尔比r_b与r_b′的关系式。

| Abstract: | The theory of sol-gel distribution and gelatinization region is a powerful tool for dealing with the structure of crosslinking networks in the molecular level in the classical theory. The present paper covers the sol-gel distribution and gelatinization of Aa-Bb(B' )b type of polycondensation and the qb'-S equation obtained from n' =TbSa/Sb. The experimental results with polyester as the model compound supports the theoretical ones of this paper. |
