METHOD FOR PRODUCING MODIFIED CONJUGATED DIENE POLYMER, MODIFIED CONJUGATED DIENE POLYMER, AND RUBBER COMPOSITION |
摘要 |
A method for producing a modified conjugated diene polymer includes carrying out a modification reaction that reacts a modifier that includes a specific compound with a conjugated diene polymer having a cis-1,4-bond content of 98.5% or more and possessing an active end to introduce the modifier into the active end of the conjugated diene polymer to obtain a modified conjugated diene polymer. The modified conjugated diene polymer that exhibits excellent wear resistance, excellent mechanical properties, and reduced cold flow can be obtained by the method. |
