This invention is directed to a catalyst and an associated process for polymerizing olefins or olefin-containing compounds, to corresponding olefin polymers, to derivatives of the olefin polymers, and to lubricant and fuel compositions that include the olefin polymers or their derivatives. The polymerization catalyst is a metal complex and optional cocatalyst where the metal complex is formed from a bidentate ligand having a nitrogen coordinating group and a second coordinating group selected from oxygen, sulfur, selenium and tellurium groups and a metal compound where the metal is a transition metal, boron, aluminum, germanium or tin. Highly branched and reactive ethylene polymers are formed from the catalyst and process of the present invention. The ethylene polymers and their derivatives are useful in various applications including as performance additives in lubricants and fuels.
