摘要 |
Catalytic component for the copolymerization of ethylene with alpha-olefins having general formula (I): (see fig. I) wherein. A is a cyclopentadienyl derivative having general formula (see fig. II) B is selected from: 1) any of the cyclopentadienyl derivatives A defined above 2) a monofunctional cyclopentadienyl radical (F) selected from cyclopentadienyl, indenyl, fluorenyl and the relative alkyl, aryl, trialkylsilyl substituted derivatives; Q, a bridge between A and B, is a bifunctional radical.
