[0235] Hereinafter, examples and comparative examples are given to explain the present invention more specifically, but the present invention is not limited to these examples.
Example Embodiment
[0236] Synthesis example 1
[0237] Into a flask equipped with a cooling tube and a stirrer, 7 parts by weight of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by weight of propylene glycol monomethyl ether acetate were charged. Then put 5 parts by weight of styrene, 20 parts by weight of methacrylic acid, and 25 parts by weight of methacrylic acid tricyclic [5.2.1.0 2,6 ] Decane-8-yl ester, 25 parts by weight of 3-(methacryloxymethyl)-3-ethyloxetane, 20 parts by weight of tetrahydrofurfuryl methacrylate, 5 parts by weight After replacing 1,3-butadiene with nitrogen, start to stir slowly. The temperature of the solution was raised to 70°C, and the temperature was maintained for 5 hours to obtain a polymer solution containing copolymer [A-1]. The solid content concentration of the obtained polymer solution was 30.0% by weight, and the weight average molecular weight of the polymer was 18,000 (the weight average molecular weight is polystyrene measured by GPC (gel permeation ...

[0238] Synthesis Example 2
[0239] Into a flask equipped with a cooling tube and a stirrer, 7 parts by weight of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by weight of diethylene glycol ethyl methyl ether were introduced. Then put 5 parts by weight of styrene, 20 parts by weight of methacrylic acid, and 25 parts by weight of methacrylic acid tricyclic [5.2.1.0 2,6 ] Decane-8-yl ester, 25 parts by weight of glycidyl methacrylate, 20 parts by weight of tetrahydrofurfuryl methacrylate, 5 parts by weight of 1,3-butadiene, after replacing with nitrogen, it starts to slow To stir. The temperature of the solution was raised to 70°C, and the temperature was maintained for 5 hours to obtain a polymer solution containing copolymer [A-2]. The solid content concentration of the obtained polymer solution was 31.0% by weight, and the weight average molecular weight of the polymer was 20,000 (the weight average molecular weight is polystyrene measured by GPC (gel permeation chromatog...
