Abstract (en)

[origin: WO0153362A1] The invention provides a metallocene procatalyst compound comprising a group 3 to 7 transition metal eta -liganded by a siloxy substituted, monocyclic, homo- or heterocyclic cyclopentadienyl group. Such compounds may be used together with a cocatalyst, e.g. an alumoxane, for olefin polymerization.
