ABSTRACT:
A process for producing a water-soluble polyelectrolyte comprising mixing acrylic acid or methacrylic acid with ammonium carbonate and a polyhydric alcohol--glycerol or ethylene glycol at a molar ratio therebetween of 2-6:1-2:1 respectively; adding hydrogen peroxide to the resulting reaction mass in an amount of from 0.1 to 1.0% by mass of the acid; polymerization of the reaction mass first at a temperature of 60.degree. to 80.degree. C. then at a spontaneous elevation of temperature to 110.degree.-140.degree. C.
