A monocyclopentadienyl or substituted monocyclopentadienyl metal complex containing compound useful as an addition polymerization catalyst corresponds to the formula: CpMXnA wherein: Cp is a single eta -cyclopentadienyl or eta -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 an eta bonding mode to the cyclopentadienyl or substituted cyclopentadienyl group; X each occurrence is hydride or a moiety selected from halo, alkyl, aryl, silyl, germyl, aryloxy, alkoxy, amide, siloxy,and combinations thereof having up to 20 non-hydrogen atoms, neutral Lewis base ligands having up to 20 non-hydrogen atoms; or optionally one X together with Cp forms a metallocycle of up to 20 non-hydrogen atoms with M; n is 1 or 2 depending on the valence of M; and A is a noncoordinating, compatible anion of a Bronsted acid salt.
