摘要： Method and apparatus for continuous preparation of an acrylonitrilebutadienestyrene copolymer comprises on-stream mounted: a prepolymerization reactor, a polymerization reactor, a reactor for the final polymerization and an apparatus for the removal of the non-polymerized monomers from the reaction mass. The polymerization reactor contains a stirring means which has a tube fixedly mounted coaxially with a shell and a mixing member disposed inside the tube. The stirring member is embodied in the form of a closed cylinder. At least one slot is provided in the tube wall. This slot is extending over the entire length of the tube. In the reactor there is also a partition positioned between the reactor shell wall and the stirring member. The partition is passing through the middle of the slot and intended for division of the reactor shell cavity into a suction zone and a pumping zone. Upon rotation of the stirring member there is effected a repeated circulation of the reaction mass within the reactor shell cavity in planes perpendicular to the longitudinal axis thereof.The present invention makes it possible to carry out the intermediate polymerization process at a constant composition of the reaction mass and a constant degree of conversion of the monomers and to obtain copolymers with various predetermined properties.
