反応手順

Borax (0.6 g.) and 50% aqueous sodium hydroxide (7.2 g.) were dissolved in 52.4 g. of distilled water. 2-acrylamido-2-methyl propyl sulfonic acid (2-AMPSA) (20.4 g.) and acrylamide (AM) (39.4 g.) were dissolved in the caustic solution while maintaining the temperature at <20° C. by cooling. The pH of the final solution was adjusted to 8.0; the solution was then combined with Tween 85 (30.0 g.) and Mentor 28 (50.0 g.). The reaction was conducted according to the procedure of Example 31. 0.5 ml of a 0.01% FAS solution and 0.1 ml of Lupersol 11 was used; polymerization was maintained at <68° C. by cooling. The product was a stable emulsion (5000 cps viscosity).
