Abstract
AbstractApparent viscosities of aqueous solutions of polyvinylbutylpyridinium bromide (DP = 2000), after correction for instrument constants, are linear in average rate of shear in the capillary viscometer. If a non‐Newtonian solute in a Newtonian solvent is assumed, the rather complicated experimental viscosity‐pressure curves at various concentrations may be summarized by the simple expression ηsp./C = z∞ (1 − αz∞β)where z∞ is ηsp./C extrapolated to zero rate of shear and β is the average velocity gradient.
