Procedure

In a reactor similar to Example 1, a monomer mixture containing 622.0 grams of acrylamide, 54.8 grams of acrylic acid, 168.4 grams of 10% NaOH and 182 grams of water was allowed to react with a catalyst mixture containing 1.3 grams of ammonium persulfate in 198 grams of water at refluxing temperature. Water was used as a solvent in amount of 1934.0 grams
