Abstract
A model is developed that describes temperature and pressure dependence of dielectric relaxation, ionic conductivity, and viscosity of glass-forming l iquids near the glass transition temperature. The expressions for ionic con ductivity are compared with experimental results for two polymer electrolyt es. Those for dielectric relaxation are compared with data for poly(propyle ne oxide) and poly(vinyl acetate). The theoretical viscosity law is compare d with experiment for propylene carbonate.
