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。
A new ethylene / maleic anhydride copolymer polyethylene glycol (PEG) polymer solid electrolyte was synthesized by using polyethylene glycol monomethyl ether with ethylene / maleic anhydride as backbone and molecular weight as 350 as side chain. The synthesis of this polymer was followed by infrared. Analysis of the final product by infrared, DSC, elemental analysis, etc. showed that the esterification reaction was complete and that the strict half-ester was formed according to the synthetic route. The product has good film-forming properties and is relatively soft. The relationship between conductivity and salt concentration has two peaks within the scope of the study. The relationship between conductivity and temperature is in accordance with the VTF behavior.
