Title:
共役ジエン重合体の製造方法
Document Type and Number:
Japanese Patent JP6480758
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a conjugated polymer capable of suppressing the adhesion of a conjugated diene polymer to guide parts provided in a device having a screw and also suppressing the thermal deterioration of the adhered conjugated diene polymer.SOLUTION: A method for producing a conjugated polymer contains: a production process of producing a mixture including a conjugated diene polymer and a solvent; and a deaerating process of deaerating the solvent using a device having a biaxial screw. The device includes guide parts, and the thermal conductivity at 100°C in the surface of the guide parts being below 50 W/m K.SELECTED DRAWING: None
