Density and Viscosity of Binary and Ternary Mixtures of Poly(ethylene glycol) and Poly(acrylic acid, sodium salt) at Temperatures of (288.15 to 318.15) K

The knowledge of physical properties and their dependency upon composition and temperature of aqueous two-phase systems is important in understanding the behavior of agitation and phase separation of such systems. In this work the viscosity and density of binary and ternary mixtures of water solutio...

Description
Summary:The knowledge of physical properties and their dependency upon composition and temperature of aqueous two-phase systems is important in understanding the behavior of agitation and phase separation of such systems. In this work the viscosity and density of binary and ternary mixtures of water solution of polyethylene glycol and sodium polyacrylate were experimentally determined at a polymer concentration range of (0.04 to 0.12) mass fraction and temperature range of (288.15 to 318.15) K. Density followed a linear behavior with temperatures and solute mass fraction. Viscosity followed a quadratic behavior with solute mass fraction and temperature for the ternary mixture. Simple polynomial functions were successfully fitted to the experimental data.
