Procedure

A 30% aqueous solution of sodium acrylate 313 g (94 g (1 mole) as sodium acrylate), styrene 10.4 g (0.1 mole), 3-mercaptopropionic acid 4.5 g and water 106 g were placed inside a reactor. After they were stirred and dissolved uniformly, the atmosphere was replaced with nitrogen. In this environment of nitrogen, the temperature of the reaction system was kept at 80° C. in a hot water bath and a polymerization process was started by dripping a 20% aqueous solution of sodium persulfate 5 g. The polymerization process was concluded after it was continued for 5 hours to obtain a 25% aqueous solution of sodium acrylate-styrene copolymer with number-average molecular weight of 1800 (Test Example 10). This will be referred to as the 25% aqueous solution of anti-bonding agent P-10.
