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Aa-Bb(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rb与rb′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′)btype of polycondensation and the qb'-S equation obtained from Tb' =TbSa/Sb. The experimental results with polyester as the model compound supports the theoretical ones of this paper.

Key words: Sol-gel distribution, Gelatinization region, Aa-Bb(B′)btype of polycondensation
