Vorschrift

To a high-pressure reactor with a magnetic stirrer is charged 31.50 g (1.75 mol) water, 13.50 g (0.232 mol) acetone, 25.0 g (7.70×10−2 mol) octadecyl acrylate, 25.0 g (0.255 mol) α-methylene-γ-butyrolactone, 1.25 g (4.08×10−3 mol) sodium stearate, and 0.13 g (5.46×10−4 mol) sodium persulfate. Two freeze-pump-thaw cycles using liquid nitrogen sufficiently degass the reaction medium prior to sealing the reactor and heating to 60° C. The reaction is stirred for 16 hours at 60° C. before cooling to room temperature and drying under vacuum at elevated temperature for isolation.
