Embodiment 1
[0062] 77.6 kg of maleic anhydride and 8.0 kg of azobisisobutyronitrile were simultaneously dissolved in 80.0 kg of butanone to prepare reaction solution A; 82.3 kg of styrene was reaction solution B.
[0063] The reaction medium in the reaction kettle is 160.0 kg butanone, and the temperature of the reaction medium in the reaction kettle is controlled at 80° C. through an oil bath. Reaction solution A and reaction solution B are continuously dripped into the reactor simultaneously with different pipelines respectively, and the feed rate of control reaction solution A is 0.460kg / min, and the feed rate of control reaction solution B is 0.229kg / min. Liquid A and reaction liquid B were added dropwise for 6 hours at the same time, and reacted for 1 hour after the dropwise addition to end the reaction. After raising the temperature and distilling butanone under reduced pressure, the material in the reactor is melted and discharged, and a solid SMA product is obtained after cooling....
Embodiment 2
[0065] Dissolve 5.4kg of azobisisobutyronitrile in 60.0kg of methyl ethyl ketone to prepare reaction solution A; 25.8kg of maleic anhydride and 82.3kg of styrene are mixed and dissolved to form reaction solution B.
[0066] The reaction medium in the reaction kettle is 103.5 kg butanone, and the temperature of the reaction medium in the reaction kettle is controlled at 70° C. through an oil bath. Reaction solution A and reaction solution B are continuously dripped into the reactor simultaneously with different pipelines respectively, and the feed rate of control reaction solution A is 0.136kg / min, and the feed rate of control reaction solution B is 0.225kg / min. Solution A and reaction solution B were added dropwise for 8 hours at the same time, and reacted for 2 hours after the dropwise addition to end the reaction. After raising the temperature and distilling butanone under reduced pressure, the material in the reactor is melted and discharged, and a solid SMA product is obta...
Embodiment 3
[0068] 19.4kg of maleic anhydride and 5.1kg of azobisisobutyronitrile were dissolved in 25.0kg of methyl ethyl ketone to prepare reaction solution A; 82.3kg of styrene was reaction solution B.
[0069] The reaction medium in the reaction kettle is 45.0 kg butanone, and the temperature of the reaction medium in the reaction kettle is controlled at 80° C. through an oil bath. Reaction solution A and reaction solution B are continuously dripped into the reactor simultaneously with different pipelines respectively, and the feed rate of control reaction solution A is 0.215kg / min, and the feed rate of control reaction solution B is 0.274kg / min. Solution A and reaction solution B were added dropwise for 5 hours at the same time, and reacted for 1 hour after the dropwise addition to end the reaction. After raising the temperature and distilling butanone under reduced pressure, the material in the reactor is melted and discharged, and a solid SMA product is obtained after cooling.
