REACTOR-POLYMERIZER Russian patent published in 2003 - IPC

FIELD: chemical industry, production of polysterene, polymethylmethacrylate and their copolymers. SUBSTANCE: reactor - polymerizer relates to chemical industry and may be used in production of polysterene, polymethylmethacrylate and their copolymers by a method of polymerization in suspension. Reactor-polymerizer for a continuous process of suspension polymerization represents the segmented pulsation apparatus. Its body is made of separate segments with ratio of a flow diameter to a segment diameter equal to 0.4 0.5. The apex angle of the diffuser part of segments makes 90 1000. At that in the top part of the body there is a expander with the cross-section exceeding cross-section of a feeding branch pipe in 4-6 times, and in the body lower part there is a collector excluding penetration of the polymerized particles into the pulsator. EFFECT: Such design of the reactor-polymerizer ensures increase of residence time of the disperse phase particles in the reaction zone of the apparatus at their ripening at the stage corresponding to 35-70% of conversion. 1 dwg
