Abstract The temperature dependence of the ionic conductivity in the PPG-rich part of the ternary system poly(propylene glycol)-poly(methyl methacrylate)-LiCF3SO3 has been investigated. The highest conductivity values, 3 x 10-5 (ohm cm)-1 at 31 °C and 4 × 10-4 (ohm cm)-1 at 77 C, were obtained for samples which had the properties of a pressure sensitive adhesive. The temperature dependence of the ionic conductivity could be well described by the Vogel-Tammann-Fulcher equation.
