Description
Summary:The applicability of cellular approach (Einstein’s and Batchelor’s formulas) to describe the viscosity of solutions as a function of the volume concentration of macromolecular coils has been analyzed on the basis of viscosity experimental data for polyvinyl alcohol solutions in dimethyl sulfoxide and water. It is shown that the Malomuzh–Orlov formula obtained for the macromolecular coils modeled as a hard core and a rarefied periphery adequately describes the viscosity of polyvinyl alcohol solutions as a function of the volume fraction of macromolecular coils in them up to the overlap concentration. The concentration dependences were obtained for the effective radius of polyvinyl alcohol macromolecules in water and dimethyl sulfoxide. It was shown that the radius of polyvinyl alcohol coils decreases nonlinearly with the growth of the solution concentration.
