Acrylamide → Isooctyl Acrylate Acrylamide Vinyl Acetate

Participants

Reaction Steps

A master batch was prepared by combining isooctyl acrylate (621.0 g), acrylamide (41.4 g), vinyl acetate (165.6 g), 2,2'azobis(2,4-dimethylpentanenitrile) (1.656 g, VAZO™ 52, DuPont), ethyl acetate (884.5 g) and methanol (87.48 g). A portion (400 g) of the resulting solution was placed in a one quart (0.95 L) amber glass bottle. The bottle was purged for 2 minutes with nitrogen at a flow rate of 1 L/min. The bottle was sealed and placed in a rotary water bath at 45° C. for 24 hours to effect essentially complete polymerization. The copolymer was diluted with ethyl acetate: methanol (90:10 v/v) to 26.05% solids and had an inherent viscosity of 1.27 deciliter/gram in ethyl acetate at 0.15 g/deciliter.
