METHOD FOR PRODUCING MODIFIED CONJUGATED DIENE POLYMER, MODIFIED CONJUGATED DIENE POLYMER, MODIFIED CONJUGATED DIENE POLYMER COMPOSITION, RUBBER COMPOSITION, AND TIRE |
摘要 |
<p>A method for producing a modified conjugated diene polymer, comprising: a polymerization step of producing a conjugated diene polymer having an active terminal using a polymerization initiator that comprises a compound having at least one nitrogen atom in the molecule and an organic lithium compound; and a modification step of reacting the active terminal of the conjugated diene polymer with a modifying agent represented by chemical formula (6). (In formula (6), R4 to R7 independently represent an alkyl group having 1 to 20 carbon atoms or an aryl group having 6 to 20 carbon atoms; R8 represents an alkylene group having 3 to 10 carbon atoms; R9 represents an alkylene group having 1 to 20 carbon atoms; m represents an integer of 1 or 2; and n represents an integer of 2 or 3.)</p> |
