BRIDGED BIPHOSPHOLES AND METALLOCENES PREPARED THEREFROM |
| 摘要 |
The invention concerns novel bridged biphosphole ligands of general formula (I), wherein: R<2>, R<3>, R<4> are selected among hydrogen, alkyl, aryl or silyl, R<1> is selected among hydrogen, alkyl, aryl or halogen, R<1> capable of being substituted by a direct bond between two phosphorus atoms and T is a divalent group. The invention also concerns metallocenes obtained from said ligands. Said metallocenes are useful as catalytic constituents of olefin polymerisation.
