実験手順

51.1 g of acrylic acid was diluted with 22.6 g of water and neutralized with 75.0 g of a 30 wt. % aqueous sodium hydroxide solution under cooling. Thereafter, 143.3 of a 40 wt. % aqueous sodium acrylamidomethylpropanesulfonate solution was added thereto, and then 7.9 g of a 5.2 wt. % aqueous potassium persulfate solution and 0.082 g of epoxy bifunctional cross linking agent (ethylene glycol diglycidyl ether) were added thereto to prepare a homogeneous solution as the aqueous monomer/initiator solution. Thereafter, the same procedure as that of Example 18 was repeated, thereby providing 131.5 g of a sodium acrylate/sodium acrylamidomethylpropanesulfonate copolymer. The resultant polymer was in the form of distorted granular particles having an average diameter of 580 μm and a bulk density of 0.44 g/ml. The measurement was conducted on the resultant polymer particles in the same manner as that of Example 4. The results are given in Table 2.
