Summary Amorphous polymer/salt mixtures based on polyvinyl alcohol and poly(hydroxyethylacrylate) and poly(hydroxyethylmethacrylate) are described. The polyvinylalcohol materials have been prepared by a solvent free hot pressing technique as well as the traditional solvent casting method. The hot pressing technique allows the production of samples which are genuinely free of solvents and thereby has allowed an assessment in this work of the effect of residual solvent on conductivity. The acrylate materials were prepared by direct polymerization of monomer/salt mixtures, thus avoiding the need for solvents. These materials have glass transitions around or well above room temperature, but nonetheless have conductivities as high as 10−7 S/cm at room temperature. The temperature and composition dependence of conductivity are also presented.
