Title
(EN) SUPPORTED OLEFIN POLYMERIZATION CATALYST
(FR) CATALYSEUR DE POLYMERISATION D'OLEFINES SUR SUPPORT
Abstract
(EN)
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.
(FR)
Constituant de catalyseur sur support pour un catalyseur de polymérisation d'oléfines, composé d'un support solide particulaire, d'un halogénure de magnésium et, éventuellement, d'un composé de métal de transition de groupe 4 ou 5, d'un composé organométallique de groupe 2 ou 13 et d'un donneur d'électrons, la majorité des particules du support solide étant constituée par un agglomérat de sous-particules. Procédé de préparation de ce constituant de catalyseur sur support. Composition de catalyseur comprenant ledit constituant et un co-catalyseur. Procédé de polymérisation d'oléfines mettant en application ladite composition.
