Title (EN) SUPPORTED CATALYST COMPONENT SUITABLE FOR ETHYLENE (CO)POLYMERIZATION, A CATALYST THEREFROM AND USE OF THE SAME
(FR) CATALYSEUR SUPPORTE SUR GEL DE SILICE SE PRETANT A LA POLYMERISATION OU A LA COPOLYMERISATION ETHYLENIQUE
Abstract: front page image
(EN)The present invention relates to a silica gel-supported catalyst component suitable for ethylene (co)polymerization, a catalyst threfrom and use of the same. The catalyst component according to the present invention is obtained by supporting the reaction product of a titanium compound, a halide promoter, a magnesium compound and an electron donor on silica gel having a larger specific surface area. When the resultant catalyst is used for ethylene polymerization, especially gas phase fluidized bed polymerization, not only the activity is substantially enhanced, but also the hydrogen response, copolymerizability of ehtylene with other alpha-olefins, and the like are improved. The catalyst is especially suitable for the fluidized bed polymerization operated in a condensed state, with high quality LLDPE resins being obtained.
(FR)L'invention concerne un catalyseur supporté sur gel de silice se prêtant à la polymérisation ou à la copolymérisation éthylénique et un catalyseur, ledit composant de catalyse est obtenu par réaction d'un composé de titane, d'un promoteur d'halogénure, d'un composé de magnésium et d'un donneur d'électrons sur un gel de silice présentant une surface spécifique plus large. Lors de l'utilisation du catalyseur dans le cadre de la polymérisation éthylénique, en l'occurrence de la polymérisation à lit fluidisé en phase gazeuse, non seulement l'activité du catalyseur est sensiblement améliorée, mais la capacité de réponse à l'hydrogène et la polymérisation éthylénique sont plus performantes. Aussi, ledit catalyseur est spécialement indiqué pour la fabrication de résine LLDPE de haute qualité faisant appel à la technique de condensation sur lit fluidisé en phase gazeuse.
