Anderson Donald R, Frisque Alvin J: Process for rapidly dissolving water-soluble polymers. Nalco Chemical Company, November 30, 1971: US3624019 (156 worldwide citation)

Water-soluble vinyl addition polymers and gums may be rapidly dissolved in water by first dispersing these polymers into a water-in-oil emulsion and then inverting these emulsions in water. The inversion of the emulsion releases the polymer into water as a solution.
