Abstract
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; PA1 a metallocene of a first transition metal, activated by an alumoxane, PA1 a contact product of dialkylmagnesium and trialkylsilanol, PA1 a second transition metal source which exhibits a hydrogen response which is different from that of the metallocene PA1 an olefin of 4 to 20 carbon atoms. This catalyst component is activated by an aluminum alkyl activator.
