Title:
METHOD FOR PRODUCING MODIFIED CONJUGATED DIENE RUBBER
Document Type and Number:
WIPO Patent Application WO/2018/088484
Kind Code:
A1
Abstract:
Provided is a method for producing a modified conjugated diene rubber, which comprises: a first step wherein a monomer containing at least a conjugated diene compound is polymerized in an inert solvent, while using an organic active metal compound as a polymerization initiator, so that a conjugated diene polymer having an active terminal is obtained; and a second step wherein the active terminal of the conjugated diene polymer having an active terminal is reacted with a compound represented by general formula (1). This method for producing a modified conjugated diene rubber is configured such that 0.15 mol or more of the compound represented by general formula (1) is used per 1 mol of metal atoms in the organic active metal compound. (In general formula (1), each of R1-R4 and R6-R9 independently represents a monovalent hydrocarbon group, a hydrogen atom or a hydroxyl group; R5 represents an arbitrary organic group, a hydrogen atom or a hydroxyl group; X1 represents a protected amino group-containing organic group that contains a primary amino group protected by a protecting group; m represents an integer of 1-500; n represents an integer of 0-499; and (m + n) is 2-500.)
