실험 절차

In a 2-L three-necked flask equipped with a stirrer, a thermometer, a reflux condenser, and a nitrogen gas introducing pipe, 360.0 g of methyl ethyl ketone was charged, and the temperature was increased to 75° C. A mixed solution containing 180 g of methyl methacrylate, 32.4 g of methoxyethyl acrylate, 126.0 g of benzyl methacrylate, 21.6 g of methacrylic acid, 72 g of methyl ethyl ketone, and 1.44 g of dimethyl-2,2-azobis(2-methylpropionate) (V-601, available from Wako Pure Chemical Industries, Ltd.) was added dropwise to the reactor at a constant speed for completing the dropwise addition in 2 hours. After the completion of the dropwise addition, a solution containing 0.72 g of “V-601” and 36.0 g of methyl ethyl ketone was added, and the resulting mixture was stirred at 75° C. for 2 hours. Thereafter, a solution containing 0.72 g of “V-601” and 36.0 g of methyl ethyl ketone was further added, and the resulting mixture was stirred at 75° C. for 2 hours. Thereafter, the temperature was increased to 85° C., and the mixture was continuously stirred for an additional 2 hours to obtain a resin solution of a methyl methacrylate/methoxyethyl acrylate/benzyl methacrylate/methacrylic acid (=50/9/35/6 [mass ratio]) copolymer.
