| 摘 要： | 采用动态力学和数学拟合相结合的方法，研究了聚环氧乙烷环氧丙烷－LiCIO4体系的离子解离与缔合。结果表明：Tg的增加依赖于盐浓度和环氧乙烷（EO）与环氧丙烷（PO）的比例，并且玻璃化转变温度（Tg）的增加可以用一个简单的溶解平衡解释，进而得出平衡常数X和离解度α。

| Abstract: | By using the method of dynamic mechanism with a kind of mathematical fit,ion dissociation and ion association in ethylene oxide-propylene oxide coplymer-LiClO4 complexes system were investigated.It was found that the increase in Tg depends on the salt concentration and ratio of EO to PO.Such plenormina can be explained by using a simple solvation equilibrium.The equilibrium constant K and the degree of dissociation α were obtained. |
