Abstract
The present invention aims at providing an olefin polymerization catalyst comprising, as a component, a transition metal compound having two ligands such as .beta.-diketone, etc. coordinated, and having excellent properties as a polymerization catalyst in the polymerization of olefins including styrene compounds. This olefin polymerization catalyst comprises: PA0 (a) a transition metal compound represented by the general formula, ##STR1## wherein M represents titanium, zirconium, hafnium or vanadium, Y.sup.1 and Y.sup.2 each represent, same or different, halogen atoms or alkyl groups containing 1 to 10 carbon atoms and R.sup.1, R.sup.2 and R.sup.3 each represent hydrogen atoms or hydrocarbon groups containing 1 to 10 carbon atoms, at least one of which is a hydrogen atom but all of which must not be hydrogen atoms, and PA0 (b) an organoaluminum compound, in particular, aluminoxane.
