METHOD OF CONTINUOUS SOLUBLE COPOLYMERIZATION AND POLYMERIZATION REACTOR FOR CARRYING IT OUT Russian patent published in 2001 - IPC

Abstract RU 2174521 C1

FIELD: chemistry of polymers. SUBSTANCE: described is method of continuous soluble copolymerization of olefins and dienes which comprises preparation of solution of gas-liquid mixture comprising monomers, hydrocarbon solvent and hydrogen, dissolution of catalyst complex components in hydrocarbon solvent, feeding of gas-liquid mixture solution into lower part of corresponding device provided with stirrer, feeding of catalyst complex component solutions therein, copolymerization during agitation of reaction mixture at elevated pressure and temperature, withdrawal of polymerizate into second similar device to continue copolymerization. Polymerizate withdrawn into second device is continuously added with copolymerization inhibitor solution in amount of 0.01-0.3% with respect to dry copolymer residue, inhibitor solution being mixed with polymerizate in turbulent stream in tubular nozzle(s). Also described is polymerization reactor for carrying it out. EFFECT: stable quality characteristics of the polymer. 2 cl, 2 dwg, 6 ex, 1 tbl
