Electrolytic Conductivity of Crystal Violet-Based Quaternary Ammonium Polyelectrolytes in Propylene Carbonate and Sulfolane
The electrolytic conductivity of crystal violet-based quaternary ammonium polyelectrolytes in very dilute solutions of propylene carbonate at 25 degrees C and sulfolane at 30 degrees C has been measured. It was not possible to determine the limiting molar conductivity, Lambda(o), from the nonlinear electrolyte conductivity, kappa, against concentration curves for the systems studied. An empirical approach based on the Lattey equation has been used to determine limiting mobilities of polycations. A modest correlation has been made with the counterion condensation and polycation conformations in order to explain the relative magnitude of limiting molar conductivities.
