Transition And Organic Metals Composition Catalysts For Addition Polymerization
(AREA)
Abstract
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.
Catalytic solid for the (co)polymerization of ethylene, process for its preparation, catalytic system for the (co)polymerization of ethylene and process
Process for producing cocatalyst composition usable for the polymerization of alpha-olefins and for producing catalyst system comprising this cocatalyst composition and for polymerization of alpha-olefin
