ABSTRACT:
The present invention relates to a process for the viscosification of an aqueous liquid which includes the steps of forming two solvent systems of an organic liquid or oil and a polar cosolvent, the polar cosolvent being less than about 15 weight percent of the solvent systems, a viscosity of both solvent systems being less than about 1,000 cps; dissolving an anionic polymer such as neutralized sulfonated polymer (water insoluble) in one of the solvent systems to form a first solution, and dissolving a cationic polymer such as a copolymer of vinyl pyridine, a concentration of the neutralized sulfonated polymer in the first solution being about 0.2 to about 10 weight percent, a concentration of the copolymer or vinyl pyridine in the second solution being about 0.2 to about 10 weight percent, a viscosity of both solutions being less than about 200 cps; mixing both solutions together to form a solution of an interpolymer complex of sulfonated polymer and vinyl pyridine polymer, and admixing or contacting said solution of said interpolymer complex with about 5 to about 500 volume percent water, the water being immiscible with the organic liquid and the polar cosolvent transferring from the organic liquid to the water phase, thereby causing the polymer containing phase to gel (i.e. thicken).
