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
It is demonstrated that the catalyst system bis(pentamethylcyclopentadienyl)-zirconium dichloride (Me 5 Cp) 2 ZrCl 2 -methylaluminoxane (MAO) is able to produce random copolymers of ethene and 1-hexene. The 1-hexene incorporation in the copolymers is extremely small. Even in the case of a molar rati
