✦ Synopsis

In the present paper, the ionic conducting properties of sulfonated poly(phenylene oxide) (PPO) and its alkali-metal salts were investigated in detail. It was found that the material had moderate conductivity, which could reach as high as 10 06 S/cm at room temperature. Its conductivity dependence on temperature conformed to the Arrhenius equation in a temperature range of 20-90ЊC. The cation's transference number determined by polarizing reversion was approximately unity. Differential scanning calorimeter, X-ray diffraction, and transmission electron microscope were used to analyze the condensed state structure of the material.

A new type of single-ion conductor with fixed cation was synthesized by spontaneous anionic polymerization of 4-vinylpyridine in the presence of short polyethylene oxide (PEO) chains as alkylating agents. These comblike polymers have low T g s and are amorphous with the shorter PEOs. Their conductiv

The polymer electrolytes composed of poly(acrylonitrile-co-lithium methacrylate) [P(AN-co-LiMA)], ethylene carbonate (EC), and LiClO 4 salts have been prepared. The ion groups in the P(AN-co-LiMA) were found to prevent EC from crystallization through their ion-dipole interactions with the polar grou
