실험 절차

56 grams 50% acrylamide, 12 grams acrylic acid and 127 grams water were mixed, and warmed up to 30° C. Nitrogen was used to purge the flask. Then 0.7 gram ammonium persulfate in 3 grams of water and 0.7 gram sodium metabisulfite in 3 grams water were added, respectively. After 20 minutes, the reaction began to take place, the temperature slowly rose to 78° C. (max.) after stirring for 1.5 hour a 20% copolymer was thus produced with an acrylamide/acrylic acid ratio of 70/30. 7 grams NaOH in 30 grams water was then added to neutralize the copolymer.
