• The fluidities of poly(ethylene oxide) (PEO)–H<SUB>2</SUB>O mixtures and the electrolytic conductivities of alkali-metal chlorides in the PEO–H<SUB>2</SUB>O mixtures were measured at different PEO compositions and temperatures (25–50 °C). The extended Walden's rule was found to be satisfied when the fluidity and conductivity were changed by the temperature variation at a constant composition, whereas a large deviation from Walden's rule was observed upon the isothermal variation of the PEO composition. The Arrhenius activation parameters were determined from the temperature dependence of the fluidities and conductivities, and some correlations between pairs of parameters were examined.
