Abstract
The effects of medium and temperature on the electrical conductivity of a polyelectrolyte sodium carboxymethylcellulose (NaCMC) in 2-butoxyethanol (BE)-water mixed solvents have been described in the light of the scaling theory of polyelectrolyte solutions. Analyses of the data indicate that the effective polyion charge initially decreases with increasing polymer concentration, which levels off afterwards. A major proportion of the current was found to be transported by the polyions. The results further demonstrated that the monomer units experience more frictional resistance in solution as the BE-content of the medium increases or as the temperature decreases. The overall results were elucidated taking the medium dielectric constant, bulk viscosity, the solvation of the polyion and counterions, and the coiling of the polyion chains into account.
