    摘要: The invention relates to a metallocene complex according to formula 1

    wherein
    M is a metal selected from lanthanides or transition metals from group 3, 4, 5 or 6 of the Periodic System of the Elements,
    Q is an anionic ligand to M,
    X is a cyclic bridging group that is bonded to a carbon atom of the cyclopentadienyl ligand and to nitrogen,
    Z 1 , Z 2 , Z 3 and Z 4 are identical or different and can be chosen from hydrogen or a hydrocarbon radicals; adjacent substituents Z can form a ring, R is chosen from hydrogen or a hydrocarbon radical with 1-20 carbon atoms.
    Also claimed are compositions comprising the metallocene complex, a process for the preparation of said complex and a process for the polymerization of olefin polymers in the presence of the metallocene complex.
    A particular embodiment is the following complex:

    formula 5
