Abstract
Provided are certain transition metal complexes which are useful as catalysts in the polymerization of olefinic monomers. In particular, the invention provides complexes of certain bidentate ligands bonded to Ni, Pd, Co, or Fe, and optionally, one or more neutral Lewis acids, and their use in the polymerization of olefins. Suitable complexes include those of the following structure: ##STR1## wherein M represents the transition metal, and Q, T, L, W, Z, R.sup.1,R.sup.2 and R.sup.10 represent functional groups.
