Acrylonitrile-styrene random copolymer production plant, the production process is: prepared by mass ratio of m (styrene): m (acrylonitrile) = 80:25, heated to 30-36 °C 25 by preheater L101, passed through filter Ml01 and mixer D101 and entered into polymerizer D102 to react. The reaction temperature is 110^115 °C, pressure is 0.22 ~0.26 MPa. Sent the materials from polymerizer to devolatilization device L102 and L103, after two times of devolatilization to remove most of the unreacted styrene and acrylonitrile, dried the material, cut, sieved, stored, packaged and obtained the finished product. The advantages of this invention are that the reaction time is reduced and the reaction rate is improved.
