SUPPORTED METALLOCENE CATALYST, ITS PREPARATION METHOD AND OLEFIN POLYMERIZATION THEREWITH

摘要

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 deep penetration and homogeneous distribution of catalyst components containing one or more metallocenes and activators within and upon porous support particles. A new process for preparing the catalyst of the invention provides for a supported metallocene catalyst, wherein (1) one or more metallocenes and activator, a solvent capable of dissolving them, and a porous support are mutually contacted to form a slurry, and (2) a sonic wave or vibrating wave in the frequency range of 1 SIMILAR 10,000 kHz is applied to a slurry, and (3) the solvent is removed, and the resultants are dried. The catalysts are useful for the olefin polymerization in a slurry and gas phase polymerization process.
