Imparting superior viscosity to aqueous polysaccharide solutions
Patent
·
OSTI ID:6170488
A method is described for imparting viscosity to an aqueous polysaccharide solution wherein the aqueous component is hard water. The method consists of prehydrating the polysaccharide in fresh or deionized water before mixing with an aqueous component of hard water. The viscosity imparted to the final aqueous solution by this method is greater than the viscosity of an aqueous polysaccharide solution hydrated initially in hard water. Alternatively, the polysaccharide solution in fresh water may be used alone or diluted with water containing inorganic ions. 8 claims.
