Acrylic Acid → Styrene acrylic acid copolymer

Participants

Reaction Conditions

Reaction Steps

A solution was prepared of acrylic acid (15.0 g, 0.2 mol) and styrene (10.4 g, 0.1 mol) in THF (200 mL). After the solution was degassed with a rapid stream of nitrogen, azobis(isobutyrylnitrile) (AIBN, 1.47 g, 3 mol % with respect to total monomer) was added. The solution was degassed for a further thirty minutes and the reaction was then heated to 70° C. for 14 h. The solution was cooled and precipitated into n-hexane (800 mL). The hexane was decanted from the fibrous white product, the product was washed with ethyl acetate (300 mL) followed by washing with a further aliquot of hexane (200 mL). The polymer was dried in vacuo to yield 21.6 g, 84.6% of a brittle white solid.
