摘要
以乙烯／马来酸酐共聚物为骨架，分子量为３５０的聚乙二醇单甲醚为侧链，合成了新型的乙烯／马来酸酐共聚物多缩乙二醇酯聚合物固体电解质。用红外对该聚合物的合成过程进行了跟踪。用红外、ＤＳＣ、元素分析等对终产物进行分析，表明酯化反应进行完全，并按合成路线生成严格的半酯。产物的成膜性能好，比较柔软，电导率与盐浓度的关系在所研究的范围内存在两个峰，电导率与温度的关系符合ＶＴＦ行为。
The SPEs of new comblike polymers based on ethylene-maleic anhydride copolymer backbone with oligo-oxyethylene side chains were synthesized according to our method. This process of synthesis was investigated by IR. The last productions were analyzed by IR、DSC、elementary analysis. The results show that the essential reaction was complete and the product from this reaction was exactly a semi-ester. The film specimens were very flexible and the comblike polymer is optimum materials of research. The relation between conductivity and salt concentration in the range of our research has two peaks, and the relation between conductivity and temperature obeys VTF behavior. The conductivity at room temperature is 10-5S·cm-1.
