[0148] Hereinafter, examples and comparative examples are shown, and the present invention will be described more specifically, but the present invention is not limited to these examples.
Synthetic example 1
[0150] In a flask equipped with a cooling tube and a stirrer, add 5 parts by weight of 2,2'-azobis(2,4-dimethylvaleronitrile), 200 parts by weight of diethylene glycol methyl ethyl ether, and then continue Pack 18 parts by weight of methacrylic acid, 40 parts by weight of glycidyl methacrylate, 5 parts by weight of styrene, 32 parts by weight of methacrylic acid tricyclic [5.2.1.0 2,6 ] Decane-8-yl, after nitrogen replacement, add 5 parts by weight of 1,3-butadiene while stirring slowly, make the solution temperature rise to 70 ° C, keep at this temperature for 5 hours and polymerize to obtain a copolymer [ A-1] solution.
[0151] The solid content concentration of the solution was 33.0% by weight, and the Mw of the copolymer [A-1] was 11,000.
Synthetic example 2
[0153] In a flask equipped with a cooling tube and a stirrer, add 7 parts by weight of 2,2'-azobis(2,4-dimethylvaleronitrile), 200 parts by weight of diethylene glycol methyl ethyl ether, and then continue Load 18 parts by weight of methacrylic acid, 20 parts by weight of glycidyl methacrylate, 5 parts by weight of styrene, 32 parts by weight of methacrylic acid tricyclic [5.2.1.0 2,6 ]decane-8-yl, 25 parts by weight of tetrahydrofurfuryl methacrylate, after nitrogen replacement, the temperature of the solution was raised to 70°C while stirring slowly, kept at this temperature for 5 hours and polymerized to obtain the copolymer [A -2] solution.
[0154] The solid content concentration of this solution was 33.4% by weight, and the Mw of the copolymer [A-2] was 9,000.
