新型梳状高分子固体电解质的研究Ⅰ．聚合物主体物的合成与表征

Studies of Solid Polymer ElectrolytesⅠ .Synthesis and Characterization of A Novel Comblike Copolymer with Oligo-Oxyethylene Side Chains

聚乙二醇单甲醚和甲醇依次与马来酸酐／乙烯基甲醚交替共聚物在溶液中两度酯化，合成了侧链长度不同的３种梳形高分子。用丁酮作为酯化反应介质可使反应完全。产物为白色橡胶状固体，成膜性较好。借助ＩＲ、１３ＣＮＭＲ和元素分析手段对产物的结构进行了确认。

A comblike polymer based on methyl vinyl etherlmaleic anhydride copolymerbackbone and with oligo-oxyetl1ylene side chins was synthesized for the first time. A two-step esterification has been carried out for polymer synthesis :reacting maleic anhydride withPEGME in methylethyl ketone at 80℃ for 24hurs and then reacting the product obtainedwith methanol in the presence of p-toluene sulfonic acid at 60℃ for 24 hours.The structureof the product was confirmed by IR,13CNMR and elemental analysis.
