Production Method for Branched Conjugated Diene-Based Polymer, Production Method for Rubber Composition, Production Method for Tire, Branched Conjugated Diene-Based Polymer, and Branched Conjugated Diene-Based Polymer Composition |
| abstract |
A production method for a branched conjugated diene-based polymer, comprising:a polymerizing step of obtaining a conjugated diene-based polymer having an active end by polymerizing or copolymerizing a conjugated diene compound, or a conjugated diene compound and an aromatic vinyl compound with an alkali metal compound or an alkaline earth metal compound used as a polymerization initiator; anda branching step of introducing a branch structure by reacting a styrene derivative as a branching agent with the active end of the conjugated diene-based polymer. |
