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.
