実験手順
To a dry 500 mL round bottom flask with a magnetic stir bar was added 1 g (3.28×10−3 mol) sodium oleate and 71.43 g (3.96 mol) water. The reaction is heated to 60° C. while stirring under nitrogen. After 10 minutes at 60° C., a monomer mixture consisting of 22.86 g (0.217 mol) 2-vinylpyridine and 21.33 g (0.217 mol α-methylene-γ-butyrolactone, as well as an aqueous mixture consisting of 1.14 g (3.74×10−3 mol) sodium oleate, 0.36 g (9.00×10−3 mol) NaOH, 0.36 g (1.51×10−3 mol) sodium persulfate, and 142.86 g (7.93 mol) water are added over 210 minutes. The polymerization is allowed to stir at 60° C. for an additional 90 minutes before cooling to room temperature and drying under vacuum for isolation.
