Abstract
Structural rheological model is used to describe the rheological behavior of hydrolyzed polyacrylamide aqueous solutions. The change in viscosity during stationary flow is explained by structure change of the polymer solution associated with contacts between macromolecules. Flow curves are well approximated by the generalized flow equation, except for the region of high shear rates, where the phenomenon of shear thickening is observed. The behavior of the rheological equation coefficients with a change in the polymer concentration is consistent with the conclusions of the structural rheological model.
