Embodiment 1
[0023] 1. Synthesis of α-Methylstyrene and Butyl Methacrylate Copolymer
[0024] 1 g AMS, 9 g BMA, and 30 g THF were successively added to a three-necked flask, 0.3 g AIBN was added at 70° C., nitrogen gas was introduced, and after 21 h of magnetic stirring, the reaction solution was mixed with methanol at a mass ratio of 3:1. Precipitate with distilled water, centrifuge; dissolve the precipitate with acetone, reprecipitate with methanol and distilled water, centrifuge, repeat 3 times, then vacuum dry and grind to obtain the copolymer of α-methylstyrene and butyl methacrylate;
