| titleOfInvention |
Group III bridged metallocene based on cyclopentadienyl-fluorenyl ligands |
| abstract |
The present invention discloses a metallocene catalyst component of formula (Flu-R″-Cp)M(η 3 -C 3 R′ 5 )(ether) n (I) wherein Cp is a cyclopentadienyl, substituted or unsubstituted, Flu is a fluorenyl, substituted or unsubstitutted, R″ is a structural bridge between Cp and Flu imparting stereorigidity to the component, M is a metal Group III of the Periodic Table, each R′ is the same or different and is hydrogen or a hydrocarbyl having from 1 to 20 carbon atoms and n is 0, 1 or 2. It further discloses a process for preparing said catalyst component and its used in the controlled polymerisation of polar or non polar monomers. |
