Title:
共役ジエン重合体組成物の製造方法
Document Type and Number:
Japanese Patent JP6754616
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a conjugated diene polymer composition containing a conjugated diene polymer having a high molecular weight which suppresses foaming and/or vent-up during a solvent-removing operation, and is reduced in an amount of a residual solvent.SOLUTION: A method for producing a conjugated diene polymer composition includes: a step I of obtaining a solution (B) of a conjugated diene polymer (A); a step II of mixing 3-50 pts.mass of a petroleum resin and/or terpene resin (C) having a number average molecular weight of 200-3,000 with respect to 100 pts.mass of the conjugated diene polymer (A) to obtain a solution (D); and a step III of directly heating and solvent-removing the mixture (D) to obtain a conjugated diene polymer composition.SELECTED DRAWING: None
