Abstract
The electrostatic contribution to the viscosity of dilute polyball solutions is calculated using the ''two-fluid'' model of colloidal liquids. A similar approach is applied to dilute and semidilute ionic solutions of rodlike polyelectrolytes, and the experimentally observed anomalous rise of the reduced viscosity with decreasing polymer concentration, the phenomenological Fuoss law, and the maximum seen at low added-salt concentration are derived.
