Synthetic example
[0178] Hereinafter, the present invention will be described more specifically by illustrating synthesis examples and examples, but the present invention is not limited to the following examples.
[0179] Copolymer Manufacture
Synthetic example 1
[0181] In the flask equipped with cooling tube and stirrer, add 5 parts by weight of 2,2'-azobisisobutyronitrile, 200 parts by weight of propylene glycol monomethyl ether acetate. Next, 50 parts by weight of glycidyl methacrylate and 50 parts by weight of styrene were added, and after replacing with nitrogen gas, stirring was started 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 a copolymer (A-1). The solid content concentration of the obtained polymer solution was 32.9% by weight.
Synthetic example 2
[0183] In the flask equipped with cooling tube and stirrer, add 5 parts by weight of 2,2'-azobisisobutyronitrile, 200 parts by weight of propylene glycol monomethyl ether acetate. Next, 50 parts by weight of (3-ethyl-3-oxyethyl) methyl methacrylate and 50 parts by weight of styrene were added, replaced with nitrogen, and then slowly stirred. The temperature of the solution was raised to 70° C., and the temperature was maintained for 5 hours to obtain a polymer solution containing a copolymer (A-2). The solid content concentration of the obtained polymer solution was 33.2% by weight.
