Reaction Steps
A reactor was charged with isooctyl acrylate (3500 g), acrylamide (263 g), methanol (614 g) and ethyl acetate (5,526 g). The mixture was deoxygenated and heated to 113° F. (45° C.). A solution of VAZO 52 (1.9 g) in ethyl acetate (150 g) was added when the temperature had stabilized at 113° F. (45° C.). Five and a half hours after the start of the reaction, a solution of VAZO 52 (1.9 g) in ethyl acetate (150 g) was added. Nine hours after the start of the reaction, a solution of VAZO 52(3.8 g) in ethyl acetate (150 g) was added. The reaction was continued at 113° F. (45° C.) until 98% minimum conversion was reached. The final polymer was diluted to 26-30% solids with ethyl acetate/methanol (90/10).
