Rotational relaxation time of rigid rod-like macromolecule in concentrated solution

M. Doi

A theory is developed on the rotational relaxation time τr of rigid rod-like molecules in concentrated solutions. The result is τ r oc c2 L9(α - cL 2 d)-2 (In (L/d))-1 , where c is the concentration of rods, L and d are the rod length and diameter respectively and α is a certain numerical factor. This relaxation time is related to the static viscosity and is found to be in good agreement with the experimental observations.
