Abstract:
A modified aluminum oxy compound (A) obtained by reacting an aluminum oxy compound (a), water (b) and a compound having a hydroxyl group (c); a polymerization catalyst component comprising the modified aluminum oxy compound; a polymerization catalyst obtained by contacting said modified aluminum oxy compound (A), a transition metal compound (B) and optionally an organoaluminum compound (C) and a specified boron compound; and a process for producing an olefin polymer or an alkenyl aromatic hydrocarbon polymer with the polymerization catalyst.
