| Research Abstract |
Static and dynamic light scattering, small-angle X-ray scattering, solution viscosity, infrared absorption, and circular dichroism measurements were made for dilute solution of linear and circular polysaccharide derivatives to determine the molecular structure and intermolecular interacrtions in various solvents. Particularly, we found that the linear and cyclic polymers have different local conformation in some polymer-solvent systems. Furthermore, both cholesteric and smectic phases were observed in different solvents.
