Catalyst composition comprising a) a metal complex with the metal Zr comprising a guanidate ligand bound to the metal of the following structure: ** Formula ** in which Z2> = NR1 R2 with R1 and R2 are independently of each other residues hydrocarbons of C1 to C40, which optionally additionally comprise, not directly adjacent to the atom of N, one or more nitrogen, oxygen and / or silicon atoms and also are optionally linked to each other or to Z1 and / or Z3; Z1 and Z3> = are independently hydrocarbon moieties of C1 to C40, optionally linked to one or more of one another or with Z2 and also optionally additionally comprise one or more nitrogen, oxygen and / or silicon atoms, but not directly adjacent to the atom of N; and b) an organoaluminum compound or an organoaluminum compound and an organocinc compound as catalyst. |
