【摘要】 基于氢键的形成和缩聚反应机理在统计意义下的相似性 ,利用高分子反应统计理论和反应动力学理论对氢键溶液的一个模型体系进行了相关讨论 .给出了体系的溶胶分数和发生溶胶 -凝胶相变的条件 ,指出质子受体基团间的竞争作用对溶胶凝胶相变点的影响 ,进而讨论了体系的数量分布函数和相关问题 .
【Abstract】 Based on the similarities between hydrogen bonding(HB) and polycondensations, we have investigated some properties of a modeling system of HB solutions by means of the statistical theory of polymeric reactions and theory of reaction dynamics. It is shown that some systems may undergo a sol-gel phase transition process under proper conditions. The gelation condition involving the critical HB degrees is given, on which the effects of compettion between the two types of proton donors are then presented. Moreover, we discussed the size distribution of HB clusters and the related problems.
