Reaction Conditions

Reaction Steps

An aqueous solution polymer of 70/30 glacial acrylic acid/2-hydroxyethyl acrylate (AA/2-HEA) was prepared by charging 600 g water, 5.6 g 50% hydrogen peroxide, 0.1 g DISSOLVINE 4.5% H—Fe (Akzo Nobel Chem. Inc.), and 0.055 g (based on 0.01% solids) SILQUEST A-171 silane (Crompton Corp., Greenwich, Conn.) to a reaction vessel. Mixtures of 59 g water and 5.5 g 50% hydrogen peroxide, and a mixture of 60 g water and 4 g erythorbic acid were then fed into the reaction vessel. A monomer feed of 364 g glacial acrylic acid, 156 g 2-hydroxyethyl acrylate, and 9.5 g 2-mercaptoethanol was then fed into the reaction vessel. A first mixture of 5.8 g water, 0.7 g 70% 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, 0.7 g 70% 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 third mixture of 5.8 g water, 0.7 g 70% 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.
