Abstract
Abstract Conductivities of NaSCN and KSCN solutions have been measured in ethanol and nitromethane in the presence of poly(oxyethylene). For poly(oxyethylene)–KSCN solutions in ethanol and nitromethane, a distinct minimum appears in conductivity vs. polymer concentration curves. In addition, for a poly(oxyethylene)–NaSCN solution in nitromethane, the conductivity curve rises steeply after passing through the minimum. These anomalies cannot be explained by the cation binding to the polymer alone, and the ionic association on the polymer chain should be taken into account at the same time. In order to analyze the results, a theory based on the duplicate ion binding on a one-dimensional lattice has been developed. The theory not only predicts the appearance of the conductivity minima, but also makes it possible to estimate the ionic association constants.
