Patent number: 4322329Abstract: The present invention relates to a process for forming a polymeric solution or gel having a viscosity of less than about 50,000 cps which includes the steps of forming a solvent system of an organic liquid and a polar cosolvent, the polar cosolvent being less than about 15 wt. % of the solvent system, a viscosity of the solvent system being less than about 1,000 cps: dissolving a neutralized sulfonated polymer in the solvent system to form a solution, a concentration of the neutralized sulfonated polymer in the solution being about 0.5 to about 20 wt. %, a viscosity of the solution being about 5 to about 5,000 cps; and adding about 1 to about 500 vol. % water to the solution having a viscosity less than about 5,000 cps, the water being immiscible with the solution and the polar cosolvent transferring from the solution phase to the water phase thereby causing the viscosity of said solution to increase by a factor of at least 2 to less than 50,000 cps.Type: GrantFiled: April 3, 1980Date of Patent: March 30, 1982Assignee: Exxon Research & Engineering Co.Inventors: Robert D.
