Document Type and Number:
Japanese Patent JP6752053
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a conjugated diene polymer capable of obtaining a conjugated diene polymer in which gel formation is suppressed, and having satisfactory moldability.SOLUTION: Provided is a method for producing a conjugated diene polymer comprising: a step I where conjugated diene monomers are polymerized to obtain a mixture (A) including a conjugated diene polymer and a solvent; a step II where the mixture (A) is subjected to de-solvent; and a step III where refrigeration drying is performed in this order, in which the temperature of the conjugated diene polymer subjected to the de-solvent in the step II is 105 to 200°C and, the temperature of the conjugated diene polymer subjected to the refrigeration drying in the step III is 40 to 100°C.SELECTED DRAWING: None
