Beschreibung
Zusammenfassung:	The invention relates to a catalyst component which is a tract 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 an olefin of 4 to 20 carbon atoms. This catalyst component is activated by an aluminum alkyl activator.
