Supported catalyst system, process for its preparation and its use for the polymerization of olefins The present invention relates to a supported catalyst system which comprises at least one metallocene component and at least one cocatalyst component and at least one modified inorganic oxide of silicon, aluminum or mixtures thereof, wherein the modified oxide contains organic silicon radicals containing at least one of the groups nitrogen, fluorine, phosphorus or sulfur.

Voici un système catalytique sur support, une méthode de préparation de ce dernier et son utilisation pour la polymérisation d'oléfines. La présente invention est liée à un système catalytique sur support qui comprend au moins un élément de métallocène, un élément de cocatalyseur et un oxyde inorganique modifié de silicium, d'aluminium ou d'un mélange des deux, dans lequel l'oxyde modifié contient des radicaux organiques de silicium qui contiennent à leur tour au moins un des groupes, soit d'azote, de fluor, de phosphore ou de soufre.
