Rheological properties of the aqueous solutions of FT-3 polysaccharide were studied by means of the creep measurement and steady flow viscosity. Salt-type FT-3 polysaccharide solutions (salt-type solutions) showed a shear thinning-type non-Newtonian flow over the range of measuring rates of shear in either case of the aqueous media with or without electrolytes. H-type FT-3 polysaccharide solutions (H-type solutions) exhibited the shear thinning flow in a range of low rates of shear, and the reduced viscosity of the H-type solutions was about one hundredth that of the salt-type solutions in the presence of electrolytes. No significant deformation due to the elastic property was observed in the creep compliance vs. time curve obtained with relatively concentrated salt-type solutions. Factors affecting the rheological properties of the polysaccharide solutions are discussed from the view point of the conformational changes mainly due to ionized carboxylic groups of the polysaccharide molecules.
