| titleOfInvention | Method for producing polybutadiene |
| abstract | (57) [Summary] [Structure] (A) An aging liquid obtained by contacting a transition metal compound with a Group I to III organometallic compound in the presence of a conjugated diene to be polymerized, and (B) carbon disulfide, Using a catalyst obtained from a compound selected from the group consisting of phenyl isothiocyanate and a xanthate compound, (C) a specific gravity of 1.1 (20 ° C.) in the presence of an inert organic solvent having a high specific gravity of 20 ° C. or more, a method of batch-wise polymerizing a monomer having a conjugated diene as a main component to be polymerized in a water-based polymerization medium, (1) A part of the (A), (B) and (C) is added to the polymerization medium to start the polymerization, and (2) the rest of the (A), (B) and (C) is continuously added. Or a method of producing polybutadiene, characterized in that the polybutadiene is maintained at a predetermined polymerization temperature by intermittently or intermittently. [Effect] A runaway reaction can be prevented and stable polymerization can be performed. Since the heat of polymerization is used to raise the temperature, a heating device for the polymerization tank is unnecessary. Also, the molecular weight of SPB can be controlled. |
