以乙烯／马来酸酐共聚物为骨架，聚乙二醇单甲醚（Ｍ＝５５０）为侧链，通过两步酯化，合成了梳状乙烯／马来酸酐共聚物多缩乙二醇酯，用ＩＲ、元素分析、交流复阻抗谱等对产物及其ＬｉＣｌＯ４盐复合物进行了研究。结果表明：所合成的产物为非晶的梳状聚合物，并严格按反应方程式生成半酯。盐浓度与电导率的关系在所研究的浓度范围内存在两个峰，一峰在Ｏ／Ｌｉ＋＝８；另一峰在Ｏ／Ｌｉ＋＝３０。用侧链ＰＥＯ玻璃化转变温度作Ｔ０，以ｌｏｇσ对１／Ｔ－Ｔ０作图，电导率与温度关系呈典型的ＶＴＦ行为，该体系室温电导率最高可达２．５８×１０－５Ｓ／ｃｍ。
The ethylene / maleic anhydride copolymer was used as the backbone and polyethylene glycol monomethyl ether (M = 550) as the side chain. Two-step esterification resulted in the synthesis of poly ethylene glycol ester of maleic anhydride copolymer The products and their LiClO4 salt complexes were studied by IR, elemental analysis and AC impedance spectroscopy. The results show that the synthesized product is an amorphous comb polymer, and the half ester is formed strictly according to the reaction equation. The relationship between salt concentration and conductivity There are two peaks in the studied concentration range, one with O / Li + = 8 and the other with O / Li + = 30. The side-chain PEO glass transition temperature T0, with logσ 1 / T-T0 plot, the conductivity and temperature showed a typical VTF behavior, the system room temperature conductivity up to 2.58 × 10-5S / cm .
