Procedure

and 100 mL of toluene, and the reactor was nitrogen-purged. The reaction liquid was heated at 70° C. for 6 hours while being stirred, and a methyl methacrylate polymer (Mw=67,800, Mn=55,900, Mw/Mn=1.21) was thereby produced. Next, 210 g (1.64 mol) of n-butyl acrylate was dripped from the dropping funnel for over 2 hours, and heating was further performed at 70° C. for 4 hours. The reaction solution was then cooled to room temperature, and poured into 1.2 L of methanol. A methyl methacrylate-n-butyl acrylate-methyl methacrylate triblock copolymer (Mn=155,000, Mw/Mn=1.28) was thereby produced. The ratio of the individual constituents was as follows: methyl methacrylate:n-butyl acrylate=31:69 (weight ratio).
