<p>CONJUGATED DIENE POLYMER, CONJUGATED DIENE POLYMER COMPOSITION, AND METHOD FOR PRODUCING CONJUGATED DIENE POLYMERA conjugated diene polymer is provided that includes a conjugated diene-based monomer unit and a monomer unit based on a compound represented by Formula (1) below, the monomer unit based on a compound represented by Formula (1) below being between a conjugated diene-based monomer unit-containing partial chain and a conjugated diene-based monomer unit-containing partial chain (said partial chain not comprising a monomer unit based on a compound represented by Formula (1) below), and the polymer having at least one terminus modified by a compound represented by Formula (2) below,[err]wherein r is 0 or 1, R¹ denotes a hydrocarbyl group or a group containing at least one atom selected from the atomic group consisting of a nitrogen atom, an oxygen atom, and a sulfur atom, and R² denotes a group containing at least one atom selected from the atomic group consisting of a nitrogen atom,an oxygen atom, and a sulfur atom, [err]wherein X denotes an oxygen atom or a sulfur atom, R³ denotes a nitrogen atom- and/or oxygen atom-containing group, a hydrocarbyl group, or a hydrogen atom, R[err] denotes a nitrogen atom- and/or oxygen atom-containing group, and R³ and R[err] may be bonded to each other. There is also provided a method for producing a conjugated diene polymer.</p> |
