Complex compounds of the general formula I a to I b with M = Ti, Zr, Hf, V, Nb, Ta, Cr, Ni, Pd; Process for the preparation of the metal complexes and the use of the complexes thus obtainable for the polymerisation and copolymerisation of olefins, for example in suspension polymerisation processes, gas phase polymerisation processes and bulk polymerisation processes. |
