The catalyst comprises a porous carrier having a particle size of 20 to 200 microns onto which has been deposited an aluminoxane and a transition metal compound having at least one cycloalkadienyl group, the transition metal being from group 4 of the Periodic Table.

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.

摘要： The present invention relates to a process for polymerizing olefins.In the process of the present invention, olefins are polymerized using a catalyst composed of a compound of a transition metal (e.g. zirconium) of Group IVB of the periodic table, an aluminoxane produced from trimethylaluminum, and an aluminoxane wherein at least one hydrocarbon group other than n-alkyl groups is bonded to an aluminum atom. The present process can polymerize olefins with excellent polymerization activity and can produce an olefin polymer having a relatively large molecular weight even when the use amount of the aluminoxane produced from trimethylaluminum (which is expensive) is small.
