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—LiClO4 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 。By using the method of dynamic mechanism with a kind of mathematical fit,ion dissociation and ion association in ethylene oxide propylene oxide coplymer LiClO 4 complexes system were investigated.It was found that the increase in T g 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.
