実験手順

To a stainless steel beaker was charged 214 g. of glacial acrylic acid (Rohm and Haas Production Grade). While stirring with a magnetic stirrer, 29% aqueous ammonia (technical) was added and the temperature was maintained at ≤35° C. until the pH became 7.5 (about 1.5 hours). Distilled water was added to bring the total weight of 428 g. The solution was transferred to a 1 liter glass beaker and while stirring 1.07 g. of methone was added (0.5% based on the acrylic acid). It dissolved in about 10 minutes. Then 23 g. of 50% acrylamide was added and the procedure of Examples 29-38 was followed to emulsion polymerize the monomers.
