| titleOfInvention | Method for polymerizing conjugated dienes |
| abstract | PROBLEM TO BE SOLVED: To provide a butadiene polymerization method for bringing a compound such as carbon disulfide into contact with a ripening solution prepared by contacting a cobalt compound and an organometallic compound or a metal hydride compound in the presence of a conjugated diene, Provided is a polymerization method which enables a polymer having a lower melting point than a conventional method to be polymerized in a higher yield. SOLUTION: (A component) It is obtained by contacting (a) a cobalt compound, (b) an organometallic compound of Group I to III or a metal hydride compound with the cobalt compound in the presence of a conjugated diene. Polymerization of a conjugated diene in which an aging solution, (B component) a compound selected from the group consisting of carbon disulfide, phenyl isothiocyanate and a xanthate compound, and (C component) a melting point modifier are brought into contact in an aqueous medium and polymerized. In the method, the amount of the (component (C)) melting point modifier is set at 0. A method for polymerizing a conjugated diene, which is 45 to 1.5 times. |
