✦ Synopsis

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. Macromolecular models constructed from a collection of spheres, cylindrical rods, circular discs, and parallelepipeds with arbitrary dimensions and relative orientations can be easily handled by this method. Comparison with available experimental data for several biopolymers shows excellent agreement. As an application to this method, we investigate the effect of surface roughness on the intrinsic viscosity of spherical particles.
