Supported metallocene catalyst for olefins (co)polymerization |
abstract |
A catalyst active in olefins polymerization is constituted by a solid component essentially constituted by: (i) a metallocene compound supported on a porous oxide of a metal M', having the following general Formula (I): <CHEM> wherein: -- M represents a metal selected from titanium, zirconium or hafnium; -- A is an anion containing an eta <5>-cyclopentadienyl ring coordinated to metal M, having a carbon atom of said ring covalently linked to metal M' of said porous oxide surface, and -- R', R'' and R''' represent, each independently, a substituent group selected from those specified in the disclosure, (ii) a co-catalyst constituted by an organic aluminum oxyderivative. Said catalyst can be obtained by an original process and is used in ethylene and other alpha-olefins polymerization and copolymerization processes. |
