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 obtaining a conjugated diene polymer containing a nitrogen atom in a polymer chain and an active end by copolymerizing a conjugated diene compound and a nitrogen atom-containing vinyl compound, or a conjugated diene compound, an aromatic vinyl compound and a nitrogen atom-containing vinyl compound by use of an alkali metal compound and/or an alkaline earth metal compound as a polymerization initiator, and
a modification step of reacting a modifier, which is a compound represented by the following formula (1), with the active end of the conjugated diene polymer: where R 1 to R 4 each independently represent an alkyl group having 1 to 20 carbon atoms or an aryl group having 6 to 20 carbon atoms; R 5 represents an alkylene group having 3 to 10 carbon atoms; R 6 represents an alkylene group having 1 to 20 carbon atoms; m is an integer of 1 or 2; and n is an integer of 2 or 3.</p> |
