Title:
PRODUCTION METHOD FOR HYDROGENATED CONJUGATED DIENE POLYMER, HYDROGENATED CONJUGATED DIENE POLYMER, POLYMER COMPOSITION, CROSSLINKED POLYMER, AND TIRE
Document Type and Number:
WIPO Patent Application WO/2017/086208
Kind Code:
A1
Abstract:
A hydrogenated conjugated diene polymer produced by a method comprising the steps of: polymerizing, in the presence of an alkali metal compound or the like, monomers including butadiene to obtain a conjugated diene polymer having an active terminal; reacting the conjugated diene polymer having an active terminal with a compound represented by formula (1); and performing hydrogenation such that the degree of hydrogenation of the butadiene-derived structural unit in the conjugated diene polymer is 80-99%. In formula (1), X1 is a silicon atom or a nitrogen atom, R1 is a single bond or an alkanediyl group, R2 is an alkanediyl group, R3 is a hydrocarbyl group, A1 is a hydrocarbyl group or a group represented by "-R4-A2", and B1 is a substituted or unsubstituted hydrocarbyl group or the like.
