摘要: 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、13C NMR和元素分析手段对产物的结构进行了确认。

Abstract: A comblike polymer based on methyl vinyl ether/maleic anhydride copolymer backbone and with oligo-oxyetl1ylene side chins was synthesized for the first time. A twostep esterification has been carried out for polymer synthesis:reacting maleic anhydride with PEGME in methylethyl ketone at 80℃ for 24 hurs and then reacting the product obtained with methanol in the presence of p-toluene sulfonic acid at 60℃ for 24 hours.The structure of the product was confirmed by IR,13C NMR and elemental analysis.
