METHOD FOR UNINTERRUPTED POLYMERIZATION OF $$$-OLEFIN Russian patent published in 1997 - IPC

Abstract RU 2100374 C1

FIELD: polymerization of $$$-olefins. SUBSTANCE: polymerization of $$$-olefin comprising 2-12 carbon atoms is carried out by contact of gaseous reaction mixture with catalyst activated by heat treatment. Catalyst is manufactured on the base of chromium oxide being combined with granulated carrier. Interaction takes place in gas-phase reactor into which components are fed at constant rate. EFFECT: improved efficiency. 12 cl, 1 dwg
