Viscosity, Density, and Refractive Index of Poly(vinylpyrrolidone)+1-Propanol and+2-Propanol at 298.15 K

The density, viscosity, and refractive index for the poly(vinylpyrrolidone) (PVP) + 1-propanol and poly(vinylpyrrolidone) + 2-propanol binary systems have been measured at 298.15 K. From the density data, the apparent specific volume of polymer and the partial specific volume of polymer and solvents have been calculated. The experimental viscosity and refractive index data have been successfully fit to a polynomial-type equation.
