MgCl 2 for use as a catalyst support was prepared by dissolution in methanol and recrystallization in n-decane, followed by vacuum-drying at 2,000 rpm. The prepared support was modified by treatment with alkylaluminum compounds. The activity profile of ethylene over the supported catalysts persisted

A silica-magnesium bisupport (SMB) was prepared by a sol-gel method for use as a support for a metallocene/Ziegler-Natta hybrid catalyst. The SMB was treated with methylaluminoxane (MAO) prior to the immobilization of TiCl 4 and rac-Et(Ind) 2 ZrCl 2 . The prepared rac-Et(Ind) 2 ZrCl 2 /TiCl 4 /MAO/S
