Title: Olefin polymerization catalyst comprising transition metal compound containing a cyclic ligand having at least two nitrogen atoms in its main chain skeleton

Abstract: An olefin-polymerizing catalyst which comprises (A) a transition metal compound having at least one cyclic amide ligand and (B) an organoaluminum compound and/or an aluminoxane compound with or without (C) an ionic compound, the catalyst component of which is simple to synthesize, and which can polymerize an olefin at a lower temperature at a lower pressure than conventional catalysts, and particularly is high in copolymerizability of .alpha.-olefins, and is particularly effective in producing ethylene/polar group-containing cyclic olefin copolymers.
