The intrinsic viscosity of dilute polymer solutions

Abstract

A general formal expression for the intrinsic viscosity of a dilute polymer solution is derived. The derivation is based on projecting the polymer dynamics onto the subspace of bilinear products of coordinates {x_iy_j}. It results in an expression composed of two terms. The first includes most of the low frequency behavior and the second all of the high frequency behavior of stiff polymers. The zero frequency limit and the Gaussian model are evaluated.
