A monocyclopentadienyl or substituted monocyclopentadienyl metal complex containing compound useful as a polymerization catalyst corresponding to the formula: CpMXn+A- wherein: Cp is a single h5-cyclopentadienyl or h5-substituted cyclopentadienyl group optionally covalently bonded to M through a sub
A monocyclopentadienyl or substituted monocyclopentadienyl metal complex containing compound useful as a polymerization catalyst corresponding to the formula: CpMXn+A- wherein: Cp is a single h5-cyclopentadienyl or h5-substituted cyclopentadienyl group optionally covalently bonded to M through a substituent; M is a metal of Group 3-10 or the Lanthanide Series of the Periodic Table bound in the h5 bonding mode to the cyclopentadienyl or substituted cyclopentadienyl group; X each occurrence independently is selected from the group consisting of hydride, halo, alkyl, aryl, silyl, germyl, aryloxy, alkoxy, amide, siloxy, neutral Lewis base ligands and combinations thereof having up to 20 non-hydrogen atoms, and optionally one X together with Cp forms a metallocycle with M; R is alkyl or aryl of up to 10 carbons; n is one or two depending on the valence of M; and A is a noncoordinating, compatible anion of a Bronsted acid salt.
A monocyclopentadienyl or substituted monocyclopentadienyl metal complex containing compound useful as an olefin polymerization catalyst corresponding to the formula: CpMXn+A- wherein: Cp is a single h5-cyclopentadienyl or h5-hydrocarbyl substituted cyclopentadienyl group optionally covalently bonde
