The intrinsic viscosities at extremely low and high rates of shear have been formularily computed of the polymer solutions and the grease for which the validity of our equation of structure viscosity has been ascertained in the previous study. From the comparisons of the intrinsic viscosity of each of these colloids at low rates of shear with its intrinsic viscosity at high rates of shear, it has been perceived that, in the case of grease (micelle-colloid) at least at very high rates of shear, the micelles of soap that act as kinetic units in the dispersion at low rates of shear should be shredded into much smaller units, while in the case of polymer solutions (molecule-colloids), the kinetic units of solute (polymer molecules) do not break down even at very high rates of shear, although, in both cases, the structure due to the mutual co-ordination between micelles or polymer molecules should of course be deemed to be broken down by shearing stress.
