摘要： The invention relates to a polymerization catalyst for alpha-olefins and a process for polymerizing alpha-olefins. The catalyst comprises a component having a transition metal compound supported on a carrier and an aluminoxane. The carrier may be pre-treated with an organometallic compound, a halogen-containing silicon compound or an aluminoxane. Alternatively, the above two catalyst components are subjected to preliminary polymerization of olefins. The catalyst of this invention enables the production of a spherical polymer having a good particle size distribution, an excellent bulk density and a narrow molecular weight distribution in a slurry polymerization method or a vapor-phase polymerization method, particulary the vapor-phase polymerization method. When applied to the copolymerization of at least two olefins, the catalyst has excellent polymerization activity such that an olefin copolymer having a narrow molecular weight distribution and a narrrow composition distribution is obtained.
