Stoichiometries have been studied for the interaction between poly(ethylene oxide) and the ammonium salts and in the polymer to salt composition range 10:1 to 2:1. A single crystalline phase having the approximate composition was identified, and an approximate phase diagram was constructed. The system is more complex, and a phase diagram was not obtained; however, at least two compounds of 8:1 and 4:1 stoichiometry are indicated. Conductivity plots indicate that the metastable amorphous phase of the various materials has a conductivity approximately 10 3 Ω −1 cm −1 higher than that of the crystalline phase at room temperature. The ion rather than H + is implicated as a charge carrier. We were not successful in determining transference numbers for anions and cations.
