Abstract: The invention relates to a metallocene complex according to formula I 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, k is the number of Q groups and equals the valence of M minus 2, R is a bridging group containing at least one carbon atom bonded to the indenyl moiety at 2-position, R1, R2, R3 and R4 are each independently chosen from the group consisting of H, a halogen atom and a C1-C20 hydrocarbylgroup, and wherein at least one of R1 and R2 is not H, and at least one of R3 and R4 is not H. The invention also relates to a catalyst comprising the metallocene complex, to a process for making polyolefins and to the use of the polyolefins for making articles.
