Versuchsvorschrift

The temperature of the 2 L-volume flask containing ethylene glycol monoethyl ether acetate was raised until the inner temperature became 80° C., and 2.30 g (0.01 mol) of polymerization initiator V-601 was further added thereto. After stirring for 5 minutes, the monomer mixed solution prepared above was added dropwise with stirring over 6 hours. After the dropwise addition, the solution was further stirred under heating for 2 hours. Thereafter, the reaction solution was cooled to room temperature and added dropwise in 3 L of hexane to precipitate a polymer. The solid collected by filtration was dissolved in 500 ml of acetone, the resulting solution was again added dropwise in 3 L of hexane, and the solid collected by filtration was dried under reduced pressure to obtain 151 g of a 4-acetoxystyrene/tert-butyl methacrylate/benzyl methacrylate copolymer.
