The role of ionic polymers in enhanced oil recovery is well recognized (1). Partially hydrolyzed polyacrylamide is the most widely used ionic polymer for this purpose as it produces a high viscosity in fresh water at a reasonable cost. However, anionic polyacrylamide rapidly looses its viscosity in solutions containing added electrolyte. In addition, polyacrylamides are sensitive to shear degradation.
