摘要：

This paper presents the results of viscosity determinations on aqueous solutions of several mammalian haemoglobins at an extremely wide range of concentrations. Rheological quantities such as the intrinsic viscosity and Huggins coefficient were calculated on the basis of the modified Mooney's formula. Using the dimensionless parameter c[eta], the existence of three characteristic ranges of concentrations was shown. By applying Lefebvre's formula for the relative viscosity in the semi-dilute regime, the Mark-Houvink exponent was evaluated.
