Electrical conductivity, differential scanning calorimetry, and nuclear magnetic resonance studies have been carried out on polyvinyl acetate after the addition of various lithium salts. In the case of lithium triflate, the resultant polymer is polyvinyl alcohol. Relatively large conductivities are observed after initial preparation, but these decrease with time when the material is in vacuum. The conductivities exhibit approximately Arrhenius behavior and increases with salt concentration. In addition to the conductivity, NMR, FTIR, and DSC results are presented. All results are interpreted in terms of the model of Wissbrun and Hannon where water is the solvating species. Author
