Zusammenfassung:The present invention relates to a new solid catalytic component, which can be used in combination with an aluminum compound as co-catalyst and optionally an external electron donor as additional co-catalyst to form a catalytic system of the Ziegler-Natta-catalyst-type. The solid catalytic system comprises titanium or vanadium compound, a compound of magnesium containing at least one halogen, a particulate porous support, and optionally an internal electron donor. La présente invention se rapporte à un nouvel élément catalyseur solide pouvant être utilisé en combinaison avec un composé d'aluminium servant de co-catalyseur, et éventuellement avec un électrodonneur servant de co-catalyseur supplémentaire, pour former un système catalyseur de type catalyseur Ziegler-Natta. Le système catalyseur solide contient un composé de titane ou de vanadium, un composé de magnésium renfermant au moins un halogène, un support poreux particulaire, et éventuellement un électrodonneur interne.
