Abstract:
A metallocene compound with the 4- and 7-positions on the indenyl moiety possessing large aromatic substituents is prepared in accordance with a method which produces substantially 100 percent racemic isomer. Advantageously, polymerization catalysts including the metallocene of the invention provide superior olefin polymerization results.
