| titleOfInvention | Method for preparing of polybutadiene |
| abstract | Disclosed is a polybutadiene production method capable of improving productivity by minimizing plugging occurring during polybutadiene production and increasing conversion ratio. The polybutadiene is produced by feeding and polymerizing a starting material containing butadiene, a polymerization catalyst and a solvent into two first polymerization reactors arranged in parallel so as to reduce plugging phenomenon, respectively, to obtain a first polymerization liquid containing a butadiene polymer A first polymerization step in which the gas produced by the heat of polymerization in the first polymerization reactor is discharged to a condenser; Supplying and polymerizing the first polymerization solution to at least one second polymerization reactor arranged in series in the first polymerization reactor to produce a second polymerization solution containing a butadiene polymer, A second polymerization step in which the gas is discharged to the condenser; And discharging the second polymerization liquid. |
