Abstract
According to the present invention there is provide a catalyst capable of affording an olefin homopolymer or copolymer having a high molecular weight and a relatively wide molecular weight distribution, in high yield, using an extremely small amount of a modified organoaluminum compound (particularly methylaluminoxane). The catalyst comprises the modified organoaluminum compound and a catalyst component comprising the following compounds (1) and (2): (1) a compound represented by the general formula R.sub.p MX.sub.4-p where M is a transition metal of Group IVa in the Periodic Table, R is cyclopentadienyl, substituted cyclopentadienyl, indenyl, substituted indenyl, or an aralkyl group having 7 to 24 carbon atoms, provided Rs may be bonded together through an alkylene groups having 2 to 8 carbon atoms and/or silylene group, X is a halogen atom, a hydrogen atom or a hydrocarbon residue having 1 to 24 carbon atoms, and p is a number satisfying the condition of 1.ltoreq.p.ltoreq.4; and (2) a compound containing carbon-fluorine bond.
