실험 절차
An aqueous polymer solution of 70/30 (glacial acrylic acid/2-hydroxylethylacrylate) was prepared by charging 600 g water, 5.6 g 50% hydrogen peroxide, 0.1 g DISSOLVINE 4.5% iron solution, and 16 g sodium hypophosphite monohydrate to a reaction vessel and heated to 70° C. A blend of 364 g glacial acrylic acid and 156 g 2-hydroxylethylacrylate (2-HEA) was uniformly added to the reactor over a three hour period using mechanical agitation. At the same time, additional mixtures of 60 g water and 5.4 g 50% hydrogen peroxide, and a mixture of 60 g water and 4 g erythorbic acid were uniformly fed into the reactor over a 3.5 hour period. After completion of the feeds, the reactor content was heated an additional 30 minutes at 70° C. The reactor was then charged with a mixture of 12 g water and 1.5 g tetrabutylhydrogen peroxide, and a mixture of 12 g water and 1 g erythorbic acid and stirred an additional 15 minutes at 70° C.
