METHOD FOR PREPARING A METALLOCENE-SUPPORTED CATALYST, AND METALLOCENE-SUPPORTED CATALYST PREPARED BY THE METHOD

WIPO Patent Application WO/2011/049349

A2

The present invention provides a method for preparing a metallocene-supported catalyst to be used in preparing polyolefins, to a metallocene-supported catalyst prepared by the method, and to a method for preparing polyolefins using the metallocene-supported catalyst. According to the present invention, catalyst components can be uniformly and deeply dispersed all over the particles of a porous carrier to improve the activity of the catalyst. Polyolefins can be prepared by means of a smooth process using the above-described catalyst, and may have high bulk density.
