摘要

AbstractMETHOD FOR PRODUCING MODIFIED CONJUGATED DIENE-BASED POLYMER, AND METHOD FOR PRODUCING VULCANIZED POLYMERA method for producing a modified conjugated diene-based polymer, wherein the method comprises:a first step of producing a conjugated diene-based polymerby polymerizing monomers comprising a conjugated diene compound 10 in a hydrocarbon solvent using an organoalkali metal compoundanda second step of adding (I) a compound having a carbonylgroup and a substituted amino group and (II) a compound representedby Formula ( II-A) to a hydrocarbon solvent containing15 the conjugated diene-based polymer.4, 71R--SHCH2)k-N R3 711(CH2)1-Si Ri2RI3) 0 (II-A)R14(CH2)m-Si R16R16
