Density Dependence of the Viscosity and Excess Volume of Aqueous Solutions of Polyvinylpyrrolidone

摘要

A model for the estimation of density dependence of the viscosity of aqueous solutions of polyvinylpyrrolidone is presented.The proposed representation of the viscosity of PVP solutions expresses the viscosity as a function density and temperature.From the density data,the excess molar volumes of this system are also calculated.
