A widespread application and nonbiodegradability of the poly(ethylene terephthalate) (PET) have created a huge amount of waste, which is imposing a serious life‐threatening environmental problem. In this study, we have utilized the PET waste to synthesize disodium terephthalate (DST), an organic salt having two Na + ions per molecule. The purity of the DST phase was confirmed by Fourier transform infrared spectroscopy, X‐ray diffractometry (XRD), and thermogravimetric analysis (TGA). A new poly(ethylene oxide)–DST polymer electrolyte was synthesized for utilizing Na + ions of the DST. The electrical conductivity of the electrolyte was optimized by varying the [O]/[Na + ] mole ratio with temperature and the results were explained using the XRD and differential scanning calorimetry studies. The TGA study showed that the electrolyte is thermally stable up to 200 °C. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136 , 47612.
