    Abstract: A stereoselective olefin polymerization catalyst contains a complex represented by Formula (1): wherein n is 2 or 3; R1 and R2 are independently an optionally substituted alkyl group or a halogen atom; L is a ligand represented by CH2R3, a halogen atom, OR4, or NR5R6; R3 is a hydrogen atom, an aromatic group, or a trialkylsilyl group; R4 is a lower alkyl group having 1 to 6 carbon atoms; and R5 and R6 are independently a hydrogen atom or a lower alkyl group having 1 to 6 carbon atoms. A method for manufacturing stereoselective polyolefin, includes polymerizing an olefin in the presence of the catalyst. The present invention provides a catalyst which enables highly isoselective polymerization generating a polymer having significantly high molecular weight and also can prepare stereoselective polyolefin with a narrow dispersity (Mw/Mn) or with a sharp molecular weight distribution, and provides a method for manufacturing stereoselective polyolefin with the catalyst.
