Abstract
The rheological properties of nematic solutions of rodlike polymers are discussed. Comparisons are made with the behavior of isotropic solution of rodlike polymers as well as that of small molecule nematogens. Evaluation of the Frank elastic constants and the Leslie-Ericksen viscosity coefficients by light scattering methods is discussed, along with theoretical prediction of the latter of rodlike systems. The nature of shear deformation over a wide range of shear rates is discussed in terms of possible flow instabilities revealed by rheological and rheo-optical observations.Keywords
