For a new double comblike ion conducting solid polymer electrolyte, bis[2-(2-methoxyethoxy)ethyl]itaconate (bis(MEE)itaconate) monomer was prepared from itaconic acid and 2-(2-methoxyethoxy)ethanol. The ion conducting polymer films were prepared by photoinitiated radical polymerization of bis(MEE)itaconate, diethyleneglycol dimethacrylate and LiClO4 with benzoin methyl ether(BME) as a photoinitiator. The plasticized polymer gel electrolytes were also prepared by photopolymerization in the presence of ethylene carbonate/propylene carbonate. EC/PC (1/1, 70 ~ 150 mol%) as a plasticizer, 5 ~ 10 % of crosslinker and concentration of alkali salt [EO]/[Li+]=10/1, 8/1 and 6/1 were used The optimum [EO]/[Li+] ratio for high ion conductivity was found to be 8. The crosslinked polymer gel alkali salt complexes showed ion conductivity 5.6 x 10-6 S/cm and the EC/PC plasticized polymer gel electrolytes showed ionic conductivity 3.6 x 10-4 S/cm. They showed a rubber elasticity and maintained a mechanical stability as a free standing film.
