Synthetic example 1
[0285] Add 3 parts by weight of 2,2'-azobisisobutyronitrile, 200 parts by weight of propylene glycol monomethyl ether acetate into a flask equipped with a cooling tube and a stirrer, then add 10 parts by weight of methacrylic acid, methyl 25 parts by weight of benzyl acrylate, 11 parts by weight of styrene, 19 parts by weight of N-phenylmaleimide, 5 parts by weight of glycerol monomethacrylate, 30 parts by weight of ω-carboxy-polycaprolactone monoacrylate parts, and 5 parts by weight of α-methylstyrene dimer as a molecular weight modifier, nitrogen substitution was performed. Thereafter, the reaction solution was stirred slowly to raise the temperature of the reaction solution to 80° C., and was kept at this temperature for 5 hours to perform polymerization to obtain a solution of a copolymer (C-1). (Mw=10,000, Mn=6,000, solid content concentration 31.2% by weight)
Synthetic example 2
[0287] In the flask equipped with a cooling tube and a stirrer, add 3 parts by weight of 2,2'-azobisisobutyronitrile, 200 parts by weight of propylene glycol monomethyl ether acetate, continue to add 15 parts by weight of methacrylic acid, methyl 35 parts by weight of benzyl acrylate, 11 parts by weight of styrene, 19 parts by weight of N-phenylmaleimide, 10 parts by weight of glycerin monomethacrylate, 10 parts by weight of ω-carboxy-polycaprolactone monoacrylate parts by weight, and 5 parts by weight of α-methylstyrene dimer as a molecular weight regulator, were replaced with nitrogen. Thereafter, the reaction solution was stirred slowly to raise the temperature of the reaction solution to 80° C., and was kept at this temperature for 5 hours to perform polymerization to obtain a solution of a copolymer (C-2). (Mw=10,500, Mn=5,200, solid content concentration 31.2% by weight)
Synthetic example 3
[0289] In the flask equipped with a cooling tube and a stirrer, add 3 parts by weight of 2,2'-azobisisobutyronitrile, 200 parts by weight of propylene glycol monomethyl ether acetate, continue to add 20 parts by weight of methacrylic acid, methyl 10 parts by weight of benzyl methacrylate, 12 parts by weight of styrene, 15 parts by weight of N-phenylmaleimide, 15 parts by weight of 2-hydroxyethyl methacrylate, 2-ethylhexyl methacrylate 28 parts by weight and 5 parts by weight of α-methylstyrene dimer as a molecular weight regulator were replaced with nitrogen. Thereafter, the reaction solution was stirred slowly to raise the temperature of the reaction solution to 80° C., and was kept at this temperature for 5 hours to perform polymerization to obtain a solution of a copolymer (C-3). (Mw=10,200, Mn=5,200, solid content concentration 31.4% by weight)
