Embodiment 1
[0020] (1) Preparation of copolymer
[0021] A 100mL three-necked bottle equipped with a thermometer and a constant pressure dropping funnel, in parts by weight (unit: gram), sequentially add 3 parts of styrene, 4 parts of glycidyl methacrylate, and 15 parts of methacrylic acid Butyl ester and 35mL toluene, under the protection of nitrogen flow, magnetic stirring, constant temperature heating to 85 ° C, 0.2 parts of azobisisobutyronitrile (AIBN) dissolved in 5mL toluene, slowly drop into the three-necked flask through the constant pressure dropping funnel , After the dropwise addition, continue heating and stirring at constant temperature for 2.5h. Add the reactants dropwise to petroleum ether (b.p. 60-90°C), and the formed white flocculent precipitate is the copolymer. The copolymer is vacuum-dried at room temperature to obtain a colorless transparent crystalline solid, which is the pure copolymer.
