Indenyl compounds and catalyst components for the polymerization of olefins

摘要

The invention relates to an indenyl compound of the general formulaR'Ind-M-(Cp)Qkin which the symbols have the following meanings: Ind: an indenyl group R': a substituent, other than hydrogen, to the Ind group, Cp: a cyclopentadienyl group M: a transition metal from group 3, 4, 5 or 6 of the Periodic System of Elements Q: a ligand to M and k is an integer linked to the valence of M. The invention is characterized in that the R' group is bound to the Ind group at the 2-position. The indenyl compound is a catalyst component for the polymerization of olefins. The invention also relates to polymers obtainable with such indenyl compounds.
