Abstract
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.
Claims10
A process for producing a metallocene useful as an olefin polymerization catalyst comprising reacting 1-(9-fluorenyl)-1-(cyclopentadienyl)-1-(methyl)-1-(but-3-enyl)methane zirconium dichloride with about two molar equivalents of n-butyl lithium in the absence of any other polymerizable composition.
