ABSTRACT:
A process for producing a water-soluble polyelectrolyte which comprises reacting acrylic acid and/or methacrylic acid with ammonium carbonate at a temperature of 15.degree.-20.degree. C. and at a molar ratio of the acrylic acids to ammonium carbonate of 1-4:1 respectively; the resulting reaction mass is added with hydrogen peroxide in an amount of 0.1-1.0% by mass of the acrylic acids and with a 5-14% aqueous solution of a joiner's glue based on animal-origin proteins in an amount of 0.7-2.0% by mass of acrylic acids as calculated for dry solids, the reaction mass is polymerized first at a temperature of 15.degree.-23.degree. C. for 30-60 minutes and then--at a spontaneous elevation of temperature to 110.degree.-130.degree. C.
