Olefin polymerization catalyst and process for olefin polymerization |
abstract |
A solid olefin polymerization catalyst comprising: a fine particle carrier; (A) a transition metal compound of a Group IVB metal of the periodic table, containing a ligand having a cyclopentadienyl skeleton; (B) an organoaluminum oxy-compound; and optionally (C) an organoaluminum compound, wherein said organoaluminum oxy-compound has an alkyl to aluminum ratio of 1.3 to 2.1; said transition metal compound (A) and said organoaluminum oxy-compound (B) and said organoaluminum compound being supported on the fine particle carrier; and said solid catalyst having a bulk density of 0.3 g/cm3 to 0.5 g/cm3 and a fluidity index of 45 to 70 and an olefin polymerization process using the olefin polymerization catalyst; and an olefin prepolymerized catalyst obtained by prepolymerizing the catalyst, and an olefin polymerization process using the olefin prepolymerized catalyst. The olefin polymerization catalyst and the olefin prepolymerization catalyst when used to carry out the polymerization of olefins hardly produces a fine-powdery polymer and a polymer showing excellent particle properties can be obtained. Moreover, the resulting olefin polymer does not stick to the wall of the polymerization reactor. |
