SYNTHESIS AND CHARACTERIZATION OF A NEW COMBLIKE POLYMER BASED ON POLY (VINYL METHYL ETHER-ALT-MALEIC ANHYDRIDE) BACKBONE

摘要

A new comblike polymer host for polymer electrolyte was synthesized by reactingmonomethyl ether of poly （ethylene glycol） with poly （vinyl methyl ether alt-maleic anhydride）and endcapping the residual carboxylic acid with methanol. Butanone was selected as a solventfor the esterification in order to obtain a completely soluble product. The synthesis processwas traced through by IR. Compared with the model compounds, the presumed structure ofthis comblike polymer has been proved to be valid by 13C NMR. The comb polymer is a whiterubbery solid. It can be dissolved in butanone and THF, and manifests good film formingability.
