Abstract:
A catalyst for polymerization of olefin, comprisinga chelated titanium compound, wherein said chelated titanium compound is produced by reacting a Mg(Râ€²mAl(ORâ€²)nR)2 compound wherein R and Râ€² are alkyl groups, with n=1, 2 or 3, and m=3âˆ’n, with a cyclopentadiene-based ligand to give a first intermediate; reacting the first intermediate with a ligand selected from the group consisting of carbodiimide-based compounds, diketiminato-based compounds, and 2-phenylamino-4-phenylimino-2-pentene and its derivatives to produce a magnesium-aluminum compound having chelated ligands; and reacting the magnesium-aluminum compound having chelated ligands with a titanium compound of TiX4, wherein X is Cl, Br, or OR, and R is an alkyl group to give said chelated titanium compound.
