We report the effect of temperature on the viscosity of dilute polyelectrolyte solutions. It has been observed that the reduced viscosity increases with dilution, reaches to a maximum and then decreases in the limit of infinite dilution. Moreover, the maximum decreases and shifts towards higher polymer concentration with increase in temperature. Thermodynamic parameters of viscous flow (Delta G(v), Delta H-v, Delta S-v) have also been calculated and discussed.
