Oligomeric metallocenes and their use |
摘要 |
A process for producing a new metallocene comprising reacting a first bridged metallocene which has an olefinically unsaturated with about two molar equivalents of an alkali metal alkyl, catalyst systems resulting from the combination of the resulting metallocenes and a cocatalyst, and polymerization processes using such catalyst systems are disclosed.
