SUPPORTED CATALYST FOR OLEFIN POLYMERIZATION, PROCESS FOR PREPARING A SUPPORTED CATALYTIC COMPONENT, A SUPPORTED CATALYTIC COMPOSITION FOR OLEFIN POLYMERIZATION AS WELL AS OLEFIN POLYMERIZATION PROCESS

摘要

A supported catalyst component for an olefin polymerization catalyst comprising a solid particulate support, a magnesium halide, and optionally a Group 4 or 5 transition metal compound, a Group 2 or 13 organometal compound, and an electron donor, wherein a majority of particles of the solid particulate support is in the form of an agglomerate of subparticles. A process for preparing this supported catalyst component. A catalyst composition comprising this catalyst component and a cocatalyst. An olefin polymerization process using such a catalyst composition.
