Abstract

A model is developed that describes temperature and pressure dependence of dielectric relaxation, ionic conductivity, and viscosity of glass-forming liquids near the glass transition temperature. The expressions for ionic conductivity are compared with experimental results for two polymer electrolytes. Those for dielectric relaxation are compared with data for poly(propylene oxide) and poly(vinyl acetate). The theoretical viscosity law is compared with experiment for propylene carbonate.
