実験手順

30.0 gm (84.1 mmoles) of glyceryl monooleate were added to a dry 100 ml, single neck, round bottom flask. A football stir bar was added and a nitrogen inlet adapter was attached. The reaction flask was placed into a room temperature oil bath and a nitrogen blanket was applied. The oil bath temperature was raised to 140° C. Once at 140° C., 8.42 gm (84.1 mmoles) succinic anhydride was added and the temperature was raised to 200° C. Heat tape was wrapped around the outside of the top of the flask and adapter to keep the succinic anhydride from subliming. The reaction was continued for 3 hours at 200° C. The flask was removed from the oil bath and allowed to cool to room temperature. The polymer was a pale yellow, viscous liquid.
