Abstract
The present invention relates to supported metallocene catalysts and to new processes for preparing them and olefin polymerization therewith. Specifically, this invention relates to supported catalyst benefiting from the penetration and homogeneous distribution of catalyst components containing one or more metallocenes and activators within porous support particles. A new process for preparing the catalyst of the invention provides for a supported metallocene catalyst, wherein one or more metallocenes and activator, a solvent capable of dissolving them and a porous support are mutually contacted to form a slurry and a sonic wave or vibrating wave in the frequency range of 1-10,000 kHz is applied to the slurry and the solvent is removed and the resultants are dried. The catalyst are useful for olefin polymerization in a slurry and gas phase polymerization process.
