실험 절차

To a 250 mL round bottom flask equipped with a magnetic stir bar is added 50 g (2.78 mol) water and 1.67 g of the surfactant Abex EP-110 (Rhodia). The mixture is heated under flowing nitrogen to 75° C., at which time a monomer mixture consisting of 14.70 g (1.50×10−1 mol) α-methylene-γ-butyrolactone, 19.55 g (1.50×10−1 mol) hydroxyethyl methacrylate, and 1.71 g (1.16×10−2 mol) 4-vinyl benzoic acid is added via syringe pump over 180 minutes at reflux. After 10 minutes of monomer mixture addition, an aqueous mixture consisting of 16.667 g (0.925 mol) water, 0.12 g (5.04×10−4 mol) sodium persulfate, is added via syringe pump over 180 minutes at reflux. After both the monomer and aqueous mixtures are completely added, the emulsion is allowed to stir for an additional 60 minutes, after which the reaction is allowed to cool to room temperature and dried under vacuum at elevated temperature for isolation.
