Title:
METHOD FOR PRODUCING CONJUGATED DIENE POLYMER
Document Type and Number:
WIPO Patent Application WO/2016/039284
Kind Code:
A1
Abstract:
The present invention provides a method for producing a conjugated diene polymer, the method having a production step for producing a conjugated diene polymer solution including a conjugated diene polymer and a solvent, and a devolatilizing step for heating the conjugated diene polymer solution while conveying the conjugated diene polymer solution through use of a device having two rotating screws and devolatilizing the solvent, the motor current value of the screws in the devolatilizing step and the motor current value of the screws during a no-load state satisfying a predetermined relational expression.
