[0725] The present invention will be described more specifically through examples below, but the present invention is not limited thereto.
Synthetic example 1
[0727] 159 g of 1-methoxy-2-propanol was added to a 1000 mL three-necked flask, and heated to 85° C. under a nitrogen stream. A solution of 63.4 g of benzyl methacrylate, 72.3 g of methacrylic acid, and 4.15 g of V-601 (Wako Pure Chemicals) was added dropwise thereto in 159 g of 1-methoxy-2-propanol over 2 hours. After completion of the dropwise addition, it was heated for 5 hours to make it react. Next, heating was stopped to obtain a copolymer of benzyl methacrylate / methacrylic acid (30 / 70 mol% ratio).
[0728] Next, 120.0 g of the above-mentioned copolymer solution was transferred to a 300 mL three-necked flask, 16.6 g of glycidyl methacrylate and 0.16 g of p-methoxyphenol were added, and stirred to dissolve. After dissolution, 3.0 g of triphenylphosphine was added, heated to 100° C., and addition reaction was carried out. After confirming the disappearance of glycidyl methacrylate by gas chromatography, heating was stopped. 1-Methoxy-2-propanol was added to prepare a so...
