“…Hence, it can be concluded that by adding salts in the solution, the polymer coil dimensions and, subsequently, solution viscosity decrease. This is in agreement with what has been reported in the literature for this copolymer …”

“…The same maximum for AAm/AAc copolymer solutions was also reported by Myagchenkov et al Based on their results of viscosity number of AAm and NaAc copolymers with respect to the degree of neutralization, near 70–80% degree of neutralization, there is a maximum for the viscosity number value because of the macroanion‐counter ion interactions.…”

SummaryAcrylamide (AAm)/Acrylic acid (AAc) copolymers are being used in a wide spectrum of applications, from which enhanced oil recovery (EOR) is the target application in this research study. The shear viscosity of the copolymer solution is extremely important in determining the performance properties of AAm/AAc copolymers. A series of copolymers with selected properties were prepared to study the effect of polymer concentration, copolymer composition, and salinity on the shear viscosity of the copolymer solutions. The results revealed the considerable effect of solution concentration and salinity on shear viscosity. Moreover, the behavior of the copolymer composition showed a maximum with respect to shear viscosity.
