A simple technique is developed for predicting the dynamic viscosity from the steady shear viscosity data of polyelectrolyte solutions. The Carreau-type viscosity equation is used to represent both the steady shear and dynamic viscosity data. A shift factor β, defined as the ratio of the dynamic time constant to the steady shear time constant, is introduced. This dimensionless parameter enables all the dynamic viscosity data to be shifted onto the steady shear viscosity curve. The parameter β correlates well with the zero shear viscosity and has the following form:
