Hydrodynamic Properties of a Plane-Polygonal Polymer, According to Kirkwood–Riseman Theory

Abstract

An exact solution of Kirkwood's formalism of transport processes for dilute polymer solutions has been found for the model of a planar rigid ring. Translational and rotatory diffusiontensors and the perturbation in the stress tensor were calculated. Non‐Newtonian behavior was found in the intrinsic viscosity, the intrinsic rigidity, and in the existence of normal stresses. In addition to the elastic response at the principal frequency ω for oscillatory fluid flow, non‐Newtonian elastic stresses appear at higher harmonics of ω .
