POLYMERIZATION REACTOR Russian patent published in 2001 - IPC

FIELD: production of polymethylmetacrylate polystyrene and their copolymers. SUBSTANCE: polymerization reactor for continuous process of suspension polymerization has a body with temperature-controlled jacket, mixing device, jet-type dispersion device, and process pipe connections. Mixing device has two tiers. Upper tier represents rotation paraboloid provided with blades, and their sizes approach those of central funnel. Lower tier is blade agitator. Jet-type dispersion device is made as a perforated tube of drop-like section. Proposed reactor provides for dispersion phase mixing without considerable deformation and crushing of particles, for exclusion of central funnel formation and consequently for reduction of agglomerate formation. EFFECT: enhanced efficiency. 4 dwg
