Versuchsvorschrift

In this procedure, 20 g (0.198 mol) methyl methacrylate, 22.30 g (0.0989 mol) 2-acetoacetoxyethyl methacrylate, and 170 g tetrahyrdrofuran (THF) were placed in a 250-ml, 3-necked flask with a nitrogen inlet, condenser, glass stopper, and stir bar. The mixture was stirred until well mixed. Next, 0.4 g 2,2′-azobis(2-methylpropionitrile) (AIBN) were added, and the resulting mixture was stirred until homogeneous. The resulting solution was heated to reflux for 24 hours under a flow of nitrogen. A colorless, viscous liquid was obtained after the reaction period. Thermogravimetric analysis (TGA) showed this to contain 40% copolymer solids.
