실험 절차
An aqueous solution polymer of 70/30 glacial acrylic acid/2-hydroxyethyl acrylate (HEA/AA) was prepared by charging 481.4 g water, 5.6 g 50% hydrogen peroxide, and 0.097 g DISSOLVINE 4.5% H—Fe (Akzo Nobel Chem. Inc., Lima, Ohio) to a reaction vessel. A monomer feed of 363.6 g glacial acrylic acid, 155.8 g 2-hydroxyethyl acrylate, and 2.11 g 2-mercaptoethanol was then fed into the reaction vessel. Additional mixtures of 58.7 g water and 5.36 g 50% hydrogen peroxide, and a mixture of 60 g water and 4.07 g erythorbic acid were then fed into the reaction vessel. A first mixture of 5.8 g water, 0.70 g tertbutylhydrogen peroxide, 5.8 g water, and 0.48 g erythorbic acid was then added to the reaction vessel, which was maintained at 70° C. A second mixture of 5.8 g water, 0.70 g tertbutylhydrogen peroxide, 5.8 g water, and 0.48 g erythorbic acid was then added to the reaction vessel, which was maintained at 72° C.
