| abstract |
The invention provides an olefin polymerization catalyst comprising an organoaluminum oxy-compound (A), a transition metal compound (B) and a hydrogenated organoaluminum compound (C); a solid olefin polymerization catalyst comprising components (A), (B), (C) and a carrier (D); a catalyst formed by prepolymerization of olefin on a catalyst comprising components (A), (B), (C) and (D); an olefin polymerization catalyst comprising the solid catalyst or the prepolymerized catalyst and an organoaluminum compound; and a method for the polymerization of olefin, which comprises polymerizing olefin in the presence of one of the catalysts. |
