Method of making high viscosity aqueous mediums
Patent
·
OSTI ID:6558904
High viscosity aqueous mediums are produced by the simultaneous addition to an aqueous solution of a major effective amount of a particulate, high molecular weight, hydratable polymer, such as hydrolyzed polyacrylamide and a minor effective amount of a particulate inorganic compound, such as bentonite. The complex formed of the polymer and the inorganic compound gives the final aqueous composition an increased viscosity. The polymer and inorganic compound are preferably added to the water by dispersing a physical admixture of the polymer and inorganic compound as discrete particles onto a moving plane of water to assure intimate contact of the polymer and compound as they contact the water.
