Versuchsvorschrift

To a high-pressure stainless steel reactor with overhead stirring is added 7.82 g (0.147 mol) of acrylonitrile, 7.82 g (7.97×10−2 mol) of α-methylene-γ-butyrolactone, 0.50 g (2.42×10−3 mol) of sodium p-styrene sulfonate and 36.88 g (2.05 mol) of water. The reactor is purged with nitrogen and 0.78 g (5.33×10−3 mol) di-tert-butyl peroxide is added to the reaction mixture before the reactor is tightly closed and heated to 160° C. After 10 minutes at 160° C., the polymerization is allowed to cool to room temperature before drying the polymer under vacuum at elevated temperature for isolation.
