METHOD OF CONTINUOUS COPOLYMERIZATION IN SOLUTION AND REACTOR FOR ITS EMBODIMENT Russian patent published in 1999 - IPC

Abstract RU 2141872 C1

FIELD: production of polymers, synthetic rubber industry, particularly, methods of production of ethylene-propylene or ethylene-propylene-diene copolymer in offered mixing reactor, and devices for embodiment of processes of copolymerization of ethylene-propylene rubbers. SUBSTANCE: method of continuous copolymerication in solution includes dissolving in hydrocarbon solvent consisting of one or more hydrocarbons, monomers and hydrogen, components of catalytic complex; supply of solution of gas-liquid mixture containing monomers, solvent and hydrogen into reactor; copolymerization with mixing of reaction mass at high pressure and temperature. Method is distinguished by preparation of catalytic complex in flow of solvent containing one or several hydrocarbons or hydrocarbon with monomers in successive turbulent mixing of catalytic complex components in tubular nozzles of reactor pipe union. Description of reactor for embodiment of the method is offered. EFFECT: simplified process, produced binary and ternary copolymers of ethylene and propylene with low content of catalytic complex in desired product. 5 cl, 1 tbl
