Abstract
The densities and viscosities of solutions of poly (vinyl alcohol)(PVA) molecular weight 125kg.moI-l in water up to 0.004% mol.kg-1 at 298.15, 308.15, 318.15 and 328.15 K have been measured. On the base of Eyring,s theory of rate processes, the molar Gibbs free energy of activation for viscous flow of solutions AGI,2.have been determined. Additionally, the viscosity coefficient Be in Jones-Dole equation is calculated. The infulence of the temperatures on the above parameter is discussed.
