摘要：The present invention relates to a continuous process for the polymerization ofan alpha-olefin having from 2 to 12 carbon atoms, which is carried out in a gas phasepolymerization reactor by bringing a gaseous reaction mixture containing the alpha-olefin to be polymerized into contact with a catalyst based on chromium oxide associatedwith a catalyst based on chromium oxide associated with a granular support and activatedby a heat treatment in which the polymerization reactor is fed with (a) alpha-olefin and (b)catalyst at constant rates.
