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 −6 S/cm at room temperature. Its conductivity dependence on temperature conformed to the Arrhenius equation in a temperature range of 20–90°C. 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. © 1997 John Wiley & Sons, Inc.
