Title:
STEREOSELECTIVE OLEFIN POLYMERIZATION CATALYST, AND STEREOSELECTIVE POLYOLEFIN PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/099583
Kind Code:
A1
Abstract:
Disclosed is a stereoselective olefin polymerization catalyst which includes a complex represented by formula (1). (In the formula: 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 C1-6 lower alkyl group; and R5 and R6 are independently a hydrogen atom or a C1-6 lower alkyl group.) Further disclosed is a stereoselective polyolefin production method which includes the polymerisation of olefins in the presence of the above catalyst. The disclosed catalyst generates particularly high molecular weight polymers, enables highly isoselective polymers, and enables the generation of stereoselective polyolefins having little dispersion (Mw/Mn), and sharp molecular weight distribution. Further disclosed is the stereoselective polyolefin production method which uses the catalyst.
