| titleOfInvention | Transition metal compound, ligand system, catalyst system and process for preparing polyolefins |
| abstract | The present invention relates to transition metal compounds of the formula (I); where M is an element of group 3, 4, 5, 6, 7, 8, 9 or 10 of the Periodic Table of the Elements or the lanthanide’s, the radicals X are identical or different and are each an organic or inorganic radical, with two radicals X also being able to be joined to one another to form a divalent radical, is 1 , 2, 3 or 4, L1 is an organic or inorganic uncharged ligand, is an integer from 0 to 4, R1 is an organic radical having from 1 to 40 carbon atoms, R2 is hydrogen or an organic radical having from 1 to 40 carbon atoms, or R1 and R2 together form a divalent organic group T1 which has from 2 to 40 carbon atoms and together with the atoms connecting its ends forms a monocyclic or polycyclic ring system which may in turn be substituted and may comprise one or more further heteroatoms selected from the group consisting of the elements O, S, Se, Te, N, P and As in the ring system, R3 is hydrogen or an organic radical having from 1 to 40 carbon atoms, R4 is hydrogen or an organic radical having from 1 to 40 carbon atoms, or R3 and R4 together form a divalent organic group T2 which has from 2 to 40 carbon atoms and together with the atoms connecting its ends forms a monocyclic or polycyclic ring system which may in turn be substituted and may comprise one or more heteroatoms selected from the group consisting of the elements O, S, Se, Te, N, P and As in the ring system, R5 is an uncharged or negatively charged organic radical which has from 1 to 40 carbon atoms and may comprise a heteroatom selected from the group consisting of the elements N, O, P, S, As and Sb, and m is an integer from 1 to 10, ligand systems having such a substitution pattern, ligand systems comprising at least one of the transition metal compounds according to the invention, a process for preparing polyolefins by polymerization or copolymerization of at least one olefin in the presence of at least one of the catalyst systems according to the invention and the use of the ligand systems according to the invention for preparing transition metal compounds. |
