  A stereoselective olefin polymerization catalyst contains a complex represented by Formula (1): wherein n is 2 or 3; R 1 and R 2 are independently an optionally substituted alkyl group or a halogen atom; L is a ligand represented by CH 2 R 3 , a halogen atom, OR 4 , or NR 5 R 6 ; R 3 is a hydrogen atom, an aromatic group, or a trialkylsilyl group; R 4 is a lower alkyl group having 1 to 6 carbon atoms; and R 5 and R 6 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.

  Use of homogeneous catalytic systems which include as a pre-catalyst a complex of a group 4 metal and a Salan ligand in the polymerization of alpha-olefins, is disclosed. The Salan ligand is characterized by a sequential diamino-containing skeleton unit which is non-symmetric, and the pre-catalysts can also be such that are devoid of a symmetry element. The disclosed polymerization results in alpha-olefin polymers such as polypropylene which are characterized by high levels of tacticity. Also disclosed are novel Salan ligands and novel complexes thereof with group 4 metals.
