A rigid linear array of beads in a Newtonian fluid is used to model a rod-like macromolecule in a dilute solution. Following the work of Kotaka, an expression is obtained relating the intrinsic viscosity to the velocity gradient. Computed results are compared with the experimental results of Str6mbe

## Abstract A method for estimating the zero shear rate viscosity for dilute solutions of rigid macromolecules with complex configurations is proposed; this method is based on the macromolecular kinetic theory of Curtiss, Bird, and Hassager.

The influence on the excess scattering function P ( p ) of fluctuations in the electron density p within a macromolecule is treated, to the approximation that the solvent is a structureless medium of constant electron density po. The results for P ( M ) and the apparent value of the mean square radi
