Effect of electrolyte concentration on viscous flow of polymer solutions
The viscosity of potassium chloride in a mixture of poly(vinyl alcohol) and water (1.0 g.L-1 to 5.0 g.L-1) was measured at different concentrations of the solute (1.0 x 10(-2) to 9.0 X 10(-2)) mol.dm(-3)at various temperatures ranging from 303 K to 323 K at intervals of 5 K. Ionic interactions in terms of Jones-Dole coefficients A and B were interpreted as a function of salt concentration, polymer concentration, and temperature. The negative values of the B-coefficient led to the conclusion that potassium chloride solution in aqueous polyvinyl alcohol behaves as a structure maker.
