PROCESS FOR RAPIDLY DISSOLVING GELS OF WATER-SOLUBLE POLYMERS BY EXTRUSION, CUTTING AND THEN SLURRYING UNDER HIGH SHEARING FORCES ABSTRACT OF THE DISCLOSURE A process for rapidly forming dilute aqueous solu- tions of water-soluble polymer from gels of such polymers is provided. In the process polymer gel is extruded, cut, and slurried in water. The slurry of gel particles is sub- jected to high shear forces immediately after slurry forma- tion to form a slurry of very fine gel particles. The slurry of fine gel particles is mixed with additional water under low shear conditions to form the dilute aqueous solu- tion of polymer. The process reduces degradation of certain important polymer properties.
