Abstract (en)

[origin: WO9806728A1] This invention relates to heteroatom substituted cyclopentadienyl-containing ligands, metal complexes containing these ligands, catalyst systems prepared from catalyst components comprising these metal complexes. The metal complexes contain a heteroatom-Cp bond or a ring heteroatom-Cp bond in the 2-position of the Cp. In preferred metal complexes the ligand is a 2-heteroatom substituted indenyl group. The catalyst systems for olefin plymerization may be used at high temperatures, are highly active and produce high molecular weight polymer.
