Abstract
The densities and viscosities of solutions of poly (vinyl alcohol)(PVA) molecular weight (14) kg.mol^-1 in water up to 0.035% mol.kg at 298.15, 308.15, 318.15 and 328.15K have been measured. On the basis of liyring s theory of rale processes, the molar Gibbs free energy of activation for viscous How of solulion delta G1 2-have been determined. Additionally, the viscosity coefficient Bc in Jones-Dole equation is calculated. The infulence of the temperature on the above parameter is discussed.
