Abstract:
A method for producing a catalyst for olefin polymerization, said method comprising the steps of:(1) reacting a compound of Mg[AlRâ€²(OR)3]2 with a chelate ligand to obtain a complex compound containing Mgâ€”Al-chelate ligand, wherein the chelate ligand is selected from a group consisting of carbodiimide compounds, 2-phenylamino-4-phenyl-imino-2-pentene, and phenylisocyanate; and (2) reacting said complex compound with a transition metal halide compound, MX4, to obtain a chelated transition metal compound, wherein R and Râ€² are independently alkyl or aryl group, M is Ti or Zr, and X is a halogen atom.
