| Abstract: | Investigations on dilute and concentrated solutions of several rodlike polymers are described. The former includes absolute and intensity fluctuation light scattering, exclusion chromatography and viscometry. The latter includes rheological properties of isotropic and anisotropic solutions. The discussion includes data for four rodlike polymers, each soluble only in strong sulphonic acids. The role of electrostic interactions and molecular association on the properties measured is considered. The similarities and differences of the rheological behaviour with that typically found with flexible chain polymers are pointed out. |
