POLYMERIZATION REACTOR Russian patent published in 2001 - IPC

FIELD: continuous polymerization reactors used for manufacture of polystyrene, polymethyl methacrylate and their copolymeters by method of polymerization in suspension. SUBSTANCE: continuous polymerization reaction consists of two sections: upper section is made in form of paraboloid of revolution whose sizes are close to sizes of central cone provided with blades and lower section is made in form of impeller agitator. Upper section of agitator has four tiers with inclined blades overlapping each other; they have different inclination of blades α₁ < α₂ < α₃ < α₄, where α₁=10 deg; α₂= 15 deg and α₄=25 deg. EFFECT: possibility of smooth distribution of dispersed phase in upper portion of apparatus without forming central cone; reduction of forming sinter cakes. 5 dwg
