ABSTRACT:
Water soluble polymers dispersed in a water-in-oil emulsion are treated to reduce the water content thereof to provide a polymer dispersed in oil which is stable to coagulation or agglomeration during subsequent treatment. The composition can be chemically modified and/or made self dissolving in water by addition of surfactant without polymer agglomeration.
