Study the Effect of adding PAAM on Some Physical Properties of PVA Polymer

Abdul-Kareem J. Al-Bermany, Asia Hussein Kadhim


Some of physical properties of dissolves Polyvinyl Alcohol (PVA) in distilled water had been studied at different concentrations (0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8% and 0.9%) (gm. /ml) before and after adding (1, 1.5) gm. Of Polyacrylamide (PAAM) for all concentrations these are (Rheological and Electrical properties). The Rheological properties such as shear Viscosity, relative Viscosity, Specific Viscosity and reduced Viscosity are measured. The results show that all these properties are increasing with the increase of the polymer concentration before and after adding except reduced Viscosity is decreasing with the increase of the polymer concentration before adding. The electrical conductivity have been investigated at (293K.). Results also shows that adding (PAAM) polymer to (PVA) enhances the conductivity, then the molar conductivity and degree of dissociation were calculated and it depending on the values of density, concentration and type of solute and solvent.

Keywords: (PVA) solution, (PAAM) solution, Rheological properties, Electrical properties.
