| titleOfInvention | Process for preparing polyolefins |
| abstract | ABSTRACT OF THE DISCLOSURE A process is provided for preparing polyolefins. The process in-cludes the steps of contacting a catalyst with an ?-olefin in the absence or presence of a liquid hydrocarbon and thereafter contacting ethylene or a mix-ture of ethylene and an ? -olefin in the gaseous phase with the treated catalyst. The catalyst comprises a solid substance and an organometallic com-pound, the solid substance containing magnesium and titanium and/or vanadium. The homopolymerization of ethylene or the copolymerization of ethylene and the ? -olefin is effected. Such vapour-phase polymerization can be carried out under extremely stable conditions, and the catalyst removal step is obviated. |
