Procedimiento

36.1 g of acrylic acid was dissolved in 16.0 g of water and neutralized with 53.0 g of a 30 wt. % aqueous sodium hydroxide solution under cooling. Thereafter, 101.3 g of a 40% aqueous sodium acrylamidomethylpropanesulfonate solution was added thereto, and 10.7 g of a 2.8 wt. % aqueous potassium persulfate solution was added thereto to prepare a homogeneous solution as an aqueous monomer/initiator solution. Thereafter, the procedure of Example 4 was repeated to provide 93.5 g of a sodium acrylate/sodium acrylamidomethylpropanesulfonate copolymer. The resultant polymer was a granular material having a distorted shape of 550 μm in the average particle diameter as measured by sieving and a bulk density of 0.45 g/ml.
