Abstract

Modified Conjugated Diene-Based Polymer, Production Method Therefor, Polymer Composition, Crosslinked Polymer, and Tire A modified conjugated diene-based polymer includes, at one terminal of a conjugated diene-based polymer chain, a polymer block having a structure derived from at least one compound selected from the group consisting of the following vinylsilane compound (A) and aromatic vinyl compound (B): (A) a vinylsilane compound having a group "-SiR1R2R3" (B) an aromatic vinyl compound containing at least one atom selected from the group consisting of a nitrogen atom, a phosphorus atom, and a sulfur atom, wherein active hydrogen is not bonded to the nitrogen atom, the phosphorus atom, or the sulfur atom.
