Sterically shielded diboron-containing metallocene olefin polymerization catalysts

Patent ·
OSTI ID:106685

A non-coordinating anion, preferably containing a sterically shielded diboron hydride, if combined with a cyclopenta-dienyl-substituted metallocene cation component, such as a zirconocene metallocene, is a useful olefin polymerization catalyst component. The anion preferably has the formula as shown in the accompanying diagram where R is branched lower alkyl, such as t-butyl.
