ABSTRACT OF THE DISCLOSURE Improved gas-phase polymerization process of .alpha.- olefin, Which is carried out under a set of the following parameters (A) to (E), (A) said gas-phase polymerization is carried out in the presence of a pre-treated catalyst composed of a solid halogen-containing titanium catalyst component supported on a magnesium compound and said organoaluminum compound, specified as in claim 1, (B) said gas-phase polymerization is carried out while maintaining the polymerization system in the fluidized state by mechanically stirring it and blowing said olefin in the gaseous state and/or a gaseous, easily volatile gaseous non-polymerizable hydrocarbon into it, (C) said olefin in the liquid state and/or a liquid, easily volatile non-polymerizable hydrocarbon is introduced into the polymerization system and while gasifying said olefin and/or said hydrocarbon in said system, said gas-phase polymerization is carried out, (D) the unreacted olefin gas and/or the hydrocarbon gas discharged from the polymerization system is partly or wholly liquefied and.recycled as the liquid olefin and/or hydrocarbon in (C), and (E) said olefin is blown or introduced into the polymerization system in at least one or B) and (C).
