Abstract: The single-ion conducting polymer electrolytes with carboxylate groups immobilized on the backbones have been synthesized by alcoholysis of maleic anhydride-styrene or maleic anhydride-vinyl acetate copolymers with PEO monomethyl ether. The plasticized comblike polymeric lithium salt film showed conductivity up to 10-6 S/cm at room temperature. The effects of polymer structure, cation radius, plasticizer, temperature and frequency on the conductivity were investigated.

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