Title: Organo-Lewis acid as cocatalyst for cationic homogeneous Ziegler-Natta olefin polymerizations

Patent ·
OSTI ID:874511

Organo-Lewis acids of the formula BR'R".sub.2 wherein B is boron, R' is fluorinated biphenyl, and R" is a fluorinated phenyl, fluorinated biphenyl, or fluorinated polycyclic fused ring group, and cationic metallocene complexes formed therewith. Such complexes are useful as polymerization catalysts.
