TL;DR: In this article, high viscosity aqueous mediums are produced by the simultaneous addition of a major effective amount of a particulate, high molecular weight, hydratable polymer, such as hydrolyzed polyacrylamide, and a minor effective amount (such as bentonite) to a mixture of a polymer and an inorganic compound.
Abstract: 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, to thereby form a complex between the polymer and the inorganic compound to give 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

TL;DR: In this paper, a method for grafting organic polymers onto inorganic colloidal substances by forming a colloid of an inorganic compound in situ in a reaction medium containing a radical polymerizable or copolymerizable vinyl-type monomer was proposed.
Abstract: A method for grafting organic polymers onto inorganic colloidal substances by (1) forming a colloid of an inorganic compound in situ in a reaction medium containing a radical-polymerizable or copolymerizable vinyl-type monomer or (2) causing a partial change in the colloidal state of previously obtained inorganic colloidal material in a reaction medium containing a vinyl-type monomer and products obtained by such method
