Title:
CONJUGATED DIENE POLYMER AND METHOD FOR PRODUCING CONJUGATED DIENE POLYMER
Document Type and Number:
WIPO Patent Application WO/2018/181176
Kind Code:
A1
Abstract:
This method for producing a conjugated diene polymer comprises step 1 for adding a polymerization initiator to a conjugated diene compound-containing monomer to obtain a polymerization solution, and step 2 for further adding the polymerization initiator once or in two or more portions to the polymerization solution to obtain a polymer having an active end, wherein a modifier having a functional group copolymerizable with the conjugated diene compound is added in step 1 and/or step 2.
