Polyacrylamides and their co polymers with other hydrophilic monomers, and their metallic salts are utilized in many applications that include mining, water treatment, sewage treatment, boiler-water additives, super absorbent diapers, paints, detergents, industrial coatings, cosmetics, ceramics, textiles, ion-exchange resins, paper making, oil well drilling, agriculture, industrial adhesives, cements, drugs delivery, and oil production. Preferably a polymerization inhibitor e.g. The finished Acrylamide may be utilized without further treatment or its viscosity... with sulfuric acid monohydrate, neutralized e.g. with calcium carbonate, maintained as a slurry without isolation, and then polymerized, preferably at pH 7 to about 9, preferably in the presence of polymerization catalyst e.g. According to invention, acrylonitrile is hydrolyzed e.g. cooper sulfate, is added with the reactants of the hydrolysis step and remove prior to polymerization. triethanolamine /ammonium persulfate.
