Multicyclic metallocycle metallocenes and their use |
摘要 |
A process for producing a metallocycle metallocene comprising reacting a reactant metallocene which has a cyclopentadienyl group having an alkenyl group attached which has at least 3 carbon atoms with about 2 molar equivalents of an alkali metal alkyl having at least 4 carbon atoms, catalyst systems resulting from the combination of the metallocycle metallocene and an organic cocatalyst, and polymerization processes using such catalyst systems are disclosed.
