CONTINUOUS SOLUTION COPOLYMERIZATION PROCESS AND POLYMERIZER FOR CONDUCTING THE PROCESS Russian patent published in 2001 - IPC

Abstract RU 2175659 C1

FIELD: polymer production. SUBSTANCE: continuous solution copolymerization process for production of ethylene-propylene or ethylenepropylene-diene copolymer, including preparation of solution of gas-liquid mixture containing hydrocarbon solvent(s) and hydrogen, dissolving catalytic complex components in hydrocarbon solvent, feeding gas-liquid mixture solution into lower section of polymerizer provided with stirring mechanism, feeding solutions of catalytic complex components into polymerizer, and copolymerization of reaction mass at stirring and elevated pressure and temperature, is distinguished in that catalytic complex component(s) is (are) dissolved in hydrocarbon solvent preliminarily cooled to a temperature by two or more times inferior to temperature of gas-liquid mixture, which is fed into polymerizer. Construction of the latter is also described. Invention can find use in synthetic rubber production area. EFFECT: enhanced process efficiency. 2 cl, 2 dwg, 1 tbl, 3 ex
