| titleOfInvention | Polymerization catalyst and method for producing conjugated diene polymer using the same |
| abstract | (57) [Problem] To provide a novel polymerization catalyst which can be used for polymerization of various monomers. The present invention also provides a method for producing a conjugated diene polymer having a high cis bond ratio, a narrow molecular weight distribution, a large number average molecular weight, and excellent mechanical and thermal properties using the polymerization catalyst. I do. SOLUTION: The cyclic ligand has two or more sulfur atoms in a main chain skeleton, and the sulfur atoms are bonded via a bonding chain containing a carbon atom, and at least one of the sulfur atoms and a cobalt atom or A thiacrown metal complex coordinated with a nickel atom, and (R 1 ) a AlZ 3-a (where R 1 is a hydrocarbon group, and Z is a hydrogen atom, a halogen atom or an alkoxyl group, a is an integer of 1 to 3), and a polymerization catalyst containing at least one compound selected from the group consisting of an organoaluminum compound and / or an aluminoxane compound represented by the following formula (1) is obtained. Polymerize. |
