Embodiment 1

[0030] Add 2 parts of styrene and 1 part of maleic anhydride into the flask, and add an appropriate amount (1%) of the initiator azobisisobutyronitrile (AIBN), fill with nitrogen, and reflux at 60-90°C for 5-10 hours. The process was carried out in a magnetic stirrer, and after the reaction was completed, it was cooled to room temperature. The reactant was precipitated in ether, filtered with suction, and dried in vacuo to obtain styrene-maleic anhydride copolymer (SMA). Show copolymer (SMA) weight average molecular weight (Mm)=18112 with gel permeation chromatography (GPC) test result, viscosity average molecular weight (Mv)=18112, number average molecular weight (Mn)=11644, Z average molecular weight (Mz) = 27191, coefficient of distribution (MWD) = 1 to 2, intrinsic viscosity (η) = 18112.1.

Embodiment 2

[0032] 1 part of styrene is copolymerized with 2 parts of maleic anhydride, the conditions are the same as in Example 1, and the obtained result is similar to that of Example 1.

Embodiment 3

[0034] 1 part of styrene is copolymerized with 1 part of maleic anhydride, the conditions are the same as in Example 1, and the obtained result is similar to that of Example 1.
