Title:
METHOD FOR PRODUCING MODIFIED CONJUGATED DIENE RUBBER
Document Type and Number:
WIPO Patent Application WO/2018/088483
Kind Code:
A1
Abstract:
Provided is a method for producing a modified conjugated diene rubber, the method comprising a first step for polymerizing, in an inert solvent, a monomer containing at least a conjugated diene compound by using an organic active metal compound as a polymerization initiator to obtain a conjugated diene polymer having an active end, and a second step for reacting a compound represented by general formula (1) with the active end of said conjugated diene polymer having the active end. (In general formula (1), R1 and R3 each independently represent a monovalent hydrocarbon group, a hydrogen atom, or a hydroxy group, R2 represents an arbitrary defined organic group, a hydrogen atom, or a hydroxy group, X1 represents a protected amino group-containing organic group containing a primary amino group protected by a protecting group, m represents an integer of 1-30, n represents an integer of 0-29, and m+n is 3-30.)
