Abstract

Abstract In accordance with the present invention, there are provided olefin polymerization catalysts comprising [A] a titanium catalyst component containing titanium, magnesium and halogen as its essential ingredients, [B-1] a transition metal compound containing a ligand having a cycloalkadienyl skeleton, [C] an organoaluminum oxy-compound and, if necessary, [D] an organoaluminum compound. Further, in accordance with the invention, there are provided olefin polymerization catalysts comprising [A] a titanium catalyst component containing titanium, magnesium and halogen as its essential ingredients, [B-2] a transition metal compound containing a ligand having a cycloalkadienyl skeleton and an anion compound containing boron, and [C] an organoaluminum oxy-compound and/or [D] an organoaluminum compound.
