乙烯－丙烯共聚物磺酸盐离聚物的研究Ⅲ　离聚物的性质

摘要: 考察了乙烯－丙烯共聚物磺酸钠离聚物的动态力学性能、力学性质和热稳定性等随离子含量的变化，讨论这些性质与离聚物结构的关系．另外，以离聚物为分离膜，用渗透蒸发方法进行乙醇－水混合液的分离，初步探讨了膜离子浓度、离子种类、实验温度和混合液组成等因素对该膜分离特性的影响。

Abstract: The influence of ion concentration on dynamic mechanical property, tensilestrength and thermal stability of ionomers based on sulfonated ethylene-proplenecopolymers has been investigated. The results show that the above properties are related to the struC
