A novel catalyst for olefin polymerization and an olefin polymerization method using the same (NOVEL POLYMERIZATION CATALYST AND PROCESS FOR POLYMERIZING OLEFIN USING THE SAME)

摘要

A novel catalyst for olefin polymerization, which comprises the following components (A), (B) and (C), and an olefin polymerization method using the same.;(A) a transition metal compound represented by the following formula (1);;R⁰_xR^One_aR²_bR³_cR⁴_dM (1);Wherein M is a transition metal selected from the group consisting of zirconium, titanium and hafnium, R^OneIs a single or double ligand, R²,R³AndR⁴A, b, c and d are each an integer of 0 to 3, with the proviso that a + b + c + d is an integer of 0 to 3, d is 4, R⁰R², R³And R⁴With a group selected from R^OneAnd X is 0 or 1), (B) an inorganic solid component carrying an organoaluminum oxy-compound having an alkyl group in a particulate inorganic solid having a hydroxyl group on its surface; And (C) an organoaluminum compound.;By using the catalyst of the present invention, an olefin polymer excellent in particulate property and various characteristics with high polymerization activity can be efficiently and efficiently produced without carrying out the prepolymerization, and the practical value is very high.
