ABSTRACT:
A method for the stabilization of both water-in-oil emulsions and solutions of poly trimethylamino methylol acrylamide is disclosed. The process consists of adding to the water-in-oil emulsion or solution containing the polymer from 10-50 mole percent of orthophosphorus acid based on the weight of the polymer. Water-in-oil emulsions of polymer are then stabilized by heating the emulsion for a period of time to obtain a stabilized emulsion of a water-soluble quaternary salt of poly trimethylamino methylol acrylamide. Solutions of poly trimethylamino methylol acrylamide need not be heated and are stablized by the addition of the orthophosphorus acid and mixing.
