• The conductivities for several solutions of alkali metal salts, such as potassium thiocyanate, containing poly(oxyethylene) (POE) have been measured as functions of the POE concentration, <I>C</I><SUB>p</SUB>. A decrease in the conductivity with an increase in <I>C</I><SUB>p</SUB> has been observed, particularly in methanol, acetonitrile, propylene carbonate, and sulfolane. For these systems, the binding of the cation has been evaluated from the decrease in conductivity and analyzed by a method based on the one-dimensional lattice model. As well as the solvent effects, the effects of the salt concentration and the effect of the alteration of salt on the binding constant have been discussed.
