PROCESS OF PREPARING CATALYST Russian patent published in 1995 - IPC

Abstract RU 2033257 C1

FIELD: catalyst preparation. SUBSTANCE: vanadium-reducing agent is placed in liquid hydrocarbon for interacting with a carrier. The agent is chosen from metall-organic substances containing a vanadium compound soluble in liquid hydrocarbon and having at least one halogen group along with an alkoxy group. The carrier contains MgCl₂ free from Mg-C bond. It also has an electron-donor compound devoid of active hydrogen. The carrier is constituted by spherical particles of a specified diameter and a narrow size distribution. EFFECT: catalyst applicable to gas-phase production of elastoplastic propylene copolymers. 6 cl, 1 tbl
