Abstract: The comblike polymers with carboxylate groups and poly(ethylene oxide)side chains have been synthesized by alcoholysis of maleic anhydride-vinyl acetate copolymers with PEO monoether. The plasticized alkali polymer salt films showed conductivity up to 10-5S/cm at room temperature. It was found that the conductivity increased when the length of the side chains increased appropriately. The effects of plasticizer, cation radius, temperature and frequency on the conductivity were also investigated.

Key words: maleic anhydride-vinyl acetate copolymer, polymer single-ion conductor, preparation, conductivity
