Procedure

An acrylamide-acrylic acid copolymer was prepared according to Canadian Pat. No. 477,265 and different from feeding procedure described in Example 2. Thus, 45.0 grams of acrylamide and 5.1 grams of acrylic acid were dissolved in 2,450 grams of distilled water. 0.5 grams of potassium persulfate were added to the solution which was then degassed under vacuum and allowed to stand in the absence of air for 7 days at room temperature.
