Rheological, Rheo-Optical and Light Scattering Studies on Nematic Solutions of Poly(1,4-Phenylene-2,6-Benzobisthiazole)

Abstract

Rheological and rheo-optical properties of mesogenic solutions of rodlike polymers are discussed. Some of the salient features of the observed behavior with isotropic solutions described, including a single-integral constitutive equation that is found to be useful, and a review of certain aspects of theoretical treatments of the viscosity of nematic fluids. The light scattering experiments are discussed, including studies on a monodomain formed with a PBT solution. Aspects of the rheological behavior of nematic solutions of PBT are considered, first for recently small strain and then for deformation with large strain rates. Reprints, Thiazoles.
