A comprehensive study of the rheological properties of aqueous polyacrylamide solutions was carried out. A RheoStress RS100 Haake rheometer was used in the measurements. The concentration of polyacrylamide ranged from 0.25 to 1.0% by weight. This range is sufficiently wide to cover many of the rheol

Rheological properties of aqueous polyacrylamide-sodium chloride solutions are studied using RheoStress RS100. Polyacrylamide concentration was varied from 0.25 to 1.0% by weight, whereas sodium chloride ranged from 0.0 to 10 g L Οͺ1 . This range of concentrations is suitable to study many of the pol
Surface tension of the polyacrylamide solution was measured as a function of the polyacrylamide concentration (0 -1000 gm/m 3 ) and temperature (10 -60Β°C). The static contact angles of the polyacrylamide solutions in the range of 0 -1000 gm/m 3 were reported on the polyvinyl chloride and Teflon subs
The molecular weight characterization of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery use is rather difficult because of its ultrahigh molecular weight copolymer and polyelectrolyte behaviors in solution. In this work the effects of aqueous NaCl solution concentration and deg
