Definitions
- the present invention relates to transition metal compounds (non-metallocenes) containing oxazoline groups in the ligand system as a catalyst component for the polymerization of olefins and to processes for their preparation and use in the polymerization of olefins.
- metallocenes in particular have been used for olefin polymerization in order to produce polyolefins with new property profiles.
- Metallocenes can be used in combination with one or more cocatalysts as a catalyst component for the polymerization and copolymerization of olefins.
- the often multi-stage synthesis and use of metallocenes still represents a significant cost factor today.
- WO 96/23010 describes transition metal complexes containing diimine groups as ligands, their preparation and their use in olefin polymerization.
- WO 00/69923 discloses individual organometallic complexes which, however, are not the subject of the present invention.
- EP-A0942010 describes further transition metal complexes containing oxazoline derivatives as ligands and their use in the polymerization of olefins
- non-metallocene complexes described in the literature are not always distinguished by an outstanding polymerization activity and, in particular, it has not yet been possible to produce isotactic polypropylene with sufficient tacticity. It was therefore the task of synthesizing new transition metal complexes which are simple and inexpensive to produce and which show high polymerization activity and stereo- and regioselectivity in the polymerization of olefins.
- ligand structures can be built up from substituted or unsubstituted oxazoline derivatives, which can react by reaction with a transition metal compound to form a transition metal complex which is suitable for the polymerization of olefins.
