Viscosity Study of Polymer Solutions through Shiio Model
A. Inigomary Rita | K. Maria Eugenie Pia
Abstract: Density, velocity and viscosity measurements were made for the solutions of Poly Vinylidene Fluoride in polar solvent for different concentrations at different temperatures. According to Shiio, the compressibility of the bound solvent cannot be neglected in the case of polymers, as it is having some appreciable value. Following this model, viscosity of the solvated part (s) is computed and the variation of s with molar concentration (n2) is studied. The methodology of arriving at the molar solvated volume (s) from (s) is verified by comparing the values of s with the value computed using the traditional equation. The correlation between Hugginss coefficient and the constants describing the solvated part is analyzed.
