Acrylamide → Acrylic acid n-decylacrylate acrylamide

Temperature

70 °C

A solution was prepared of acrylic acid (10.0 g, 133 mmol), n-decylacrylate (3.0 g, 14.2 mmol) and acrylamide (3.0 g, 42.2 mmol) in dioxane (200 mL). After the solution was degassed with a rapid stream of nitrogen, AIBN (1.3 g) was added. The solution was degassed for a further thirty minutes and the reaction was then heated to 70° C. for 17 h. The polymer precipitated as a fibrous white solid as the reaction proceeded. The solution was cooled and the dioxane decanted. The residue was washed with ethyl acetate (600 mL) and the ethyl acetate was discarded. The polymer was finally washed with hexanes (300 mL) and dried in vacuo.
