Olefin polymerization catalyst and process for olefin polymerization |
摘要 |
<p>The present invention provides an olefin polymerization catalyst having a bulk density of not less than 0.3 g/cm<3> and a fluidity index of not less than 45 comprising: a fine particle carrier; (A) a transition metal compound of Group IVB metal of the periodic table, containing a ligand having a cyclopentadienyl skeleton; (B) an organoaluminum oxy-component; and optionally (C) an organoaluminum compound; said transition metal compound (A), said organoaluminum oxy-component (B) and said organoaluminum compound (C) being supported on the fine particle carrier. Also provided is a prepolymerized olefin polymerization catalyst having a bulk density of not less than 0.3 g/cm<3> and a fluidity index of not less than 45 comprising: a fine particle carrier; (A) a transition metal compound of Group IVB metal of the periodic table, containing a ligand having a cyclopentadienyl skeleton; (B) an organoaluminum oxy-component; (C) an organoaluminum compound; and an olefin polymer produced by prepolymerization and a polymerization process using the catalyst.</p> |
