A process for the polymerization of olefins using a metal complex of group 3, 4, 5, 6, 7, 8, 9 or 10 of the Periodic Table comprising at least one group C&#x2550;NR, C&#x2550;PR, C&#x2550;O, C&#x2550;S or a heteroaromatic ring system containing at least one atom from the group consisting of N, P, O and S, can be used for controlling the width of the molar mass distribution of the resulting polymers.

Method of polymerization of olefins

Cyclopentadienyl complexes of group 6 having at least one cyclopentadienyl system which is substituted by at least one silyl group which bears at least one halogen substituent and a catalyst system comprising at least one of the cyclopentadienyl complexes, and also a process for preparing them, the use of the catalyst system for the polymerization or copolymerization of olefins and a process for preparing polyolefins by polymerization or copolymerization of olefins in the presence of the catalyst system.

Cyclopentadienyl complexes of group 6 substituted by silyl halides

Monocyclopentadienyl complexes in which the cyclopentadienyl system is substituted by at least one bridged donor, where the bridge contains at least one atom of group 14 of the Periodic Table and at least one atom of group 15 or 16 of the Periodic Table, and a catalyst system comprising at least one of the monocyclopentadienyl complexes, and also methods of preparing them, the use of the catalyst system for the polymerization or copolymerization of olefins and a process for preparing polyolefins by polymerization or copolymerization of olefins in the presence of the catalyst system and the preparation of the associated cyclopentadienyl system.

Monocyclopentadienyl complexes

Monocyclopentadienyl complexes in which the cyclopentadienyl system bears at least one bridged donor and at least one aryl group and a catalyst system comprising at least one of the monocyclopentadienyl complexes, and also processes for preparing them, the use of the catalyst system for the polymerization or copolymerization of olefins and a process for preparing polyolefins by polymerization or copolymerization of olefins in the presence of the catalyst system and the preparation of the associated cyclopentadienyl system.
