shearing and dispersion process for the rapid under high shear force. dissolution of water-soluble gel polymers by extrusion.

摘要

A process for rapidly forming dilute aqueous solutions 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 subjected to high shear forces immediately after slurry formation 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 solution of polymer. The process reduces degradation of certain important polymer properties.
