Embodiment

[0346] The present invention will be described in further detail with reference to the following examples, but the present invention is not limited to these examples.

[0347] In the examples, EA, BA, MEA, MMA, TSMA, DSMA, GMA, SMA, IBMA, 2EHA, HEA, TBMA, and MA represent: ethyl acrylate, butyl acrylate, 2-methoxyethyl acrylate , methyl methacrylate, γ-(methacryloxypropyl) trimethoxysilane, γ-(methacryloxypropyl) dimethoxymethylsilane, glycidyl methacrylate, methyl stearyl acrylate, isobornyl methacrylate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, tert-butyl acrylate, and methacrylic acid.

[0349] (molecular weight)

[0350] The molecular weight of the block copolymer was measured with a GPC analysis apparatus (system: GPC system manufactured by Waters, column: Shodex K-804 (polystyrene gel) manufactured by Showa Denko K.K.). The molecular weight calculated as polystyrene was determined using chloroform as the mobile phase.

[0357] (Synthesis of MMA-BA-MMA type block copolymer)

[0358] 112.56 g of copper(I) bromide was added to a 50 L reactor, and the atmosphere in the reactor was replaced with nitrogen. A solution obtained by previously mixing 627.44 g of acetonitrile and 1072.8 g of butyl acrylate was charged into a reactor whose interior was kept under reduced pressure, and then the temperature was raised to 65° C. and stirred for 30 minutes. Thereafter, a solution obtained by dissolving 56.50 g of diethyl 2,5-dibromoadipate in 6973.2 g of butyl acrylate and 158.76 g of butyl acetate, and 784.30 g of acetonitrile were added to the reactor, and the temperature was then raised to 85°C and stirred for an additional 30 minutes. Polymerization of butyl acrylate as the first block was initiated by adding 16 ml of pentamethyldiethylenetriamine.

[0359] When the conversion reached 95%, 14228.8 g of toluene, 77.68 g of copper(I) chloride, and 5182.5 g of methyl methacrylate were added to the reactor...

[0365] Synthesis of (MMA-co-GMA)-b-BA-b-(MMA-co-GMA) type block copolymer (also known as MMA-BA-MMA type block copolymer containing epoxy groups)

[0366] After replacing the inside of the polymerization vessel of the 500 ml separable flask with nitrogen, 1.32 g (9.2 mmol) of copper bromide (copper (I) bromide, hereinafter the same substance will be used) was weighed into the vessel, and added to the 20 ml of acetonitrile (dried over molecular sieves and bubbled with nitrogen) were added thereto. After heating at 70° C. for 5 minutes under stirring, the whole equipment was cooled to room temperature and 0.63 g (1.7 mmol) of initiator, 2,5-dibromoadipate, and 89.4 g (100 ml) of diethyl adipate were added thereto. BA. After heating the mixture at 80°C under stirring, pentamethyldiethylenetriamine (hereinafter abbreviated as triamine) forms a catalyst in the system by adding 0.19 ml (0.9 mmol) of a ligand therein, thereby initiating polymerization. At intervals, for example, 3...
