The invention relates to a catalyst component which is a contact product of reagents comprising: silica which has a pore volume which exceeds 2.9 cc/gram and an average pore diameter which exceed 400 Angstroms; a metallocene of a first transition metal, activated by an alumoxane; a contact product of dialkylmagnesium and trialkylsilanol; a second transition metal source which exhibits a hydrogen response which is different from that of the metallocene; and an olefin of 4 to 20 carbon atoms. This catalyst component is activated by an aluminum alkyl activator.
Cette invention se rapporte à un composant de catalyseur qui est un produit de contact de réactifs comprenant: de la silice possédant un volume des pores supérieur à 2,9 cm?3¿/gramme et un diamètre moyen des pores supérieur à 400 Angströms; un métallocène d'un premier métal de transition, activé par un alumoxane; un produit de contact de dialkylmagnésium et de trialkylsilanole; une source d'un second métal de transition qui possède une réponse à l'hydrogène qui est différente de celle du métallocène; et une oléfine de 4 à 20 atomes de carbone. Ce composant de catalyseur est activé par un activateur alkylé à l'aluminium.
