Methanol → Isooctyl Acrylate Acrylamide Vinyl Acetate

Participants

Reaction Conditions

Reaction Steps

Isooctyl acrylate (IOA) (75 g), acrylamide (ACM) (5 g), vinyl acetate (VOAc) (20 g), ethyl acetate (136.5 g), and methanol (13.5 g) were added to a 1 quart vessel and the vessel was purged with nitrogen (2 minutes, 1.5 liters per minute nitrogen flow). 2,2′-azobis(2,4-dimethylvaleronitrile) (0.05 g) was added and the reaction was agitated at 42° C. for 6 hours. An additional portion of 2,2′-azobis(2,4-dimethylvaleronitrile) (0.05 g) was added and the vessel was again purged with nitrogen (2 minutes, 1.5 liters per minute nitrogen flow). The reaction was maintained at 42° C. for an additional 22 hours. The temperature was raised to 57° C. and the reaction was maintained an additional 6 hours. The resulting polymerization reaction product was diluted with ethyl acetate (30.6 g) and methanol (5 g). The percent solids of the resultant copolymer solution was 31 weight %. The measured inherent viscosity was 1.34 dL/g.
