Abstract
Disclosed are a conjugated diene-based polymer from which a polymer composition excellent in fuel cost-saving properties and elongation at break can be obtained, a polymer composition containing the conjugated diene-based polymer and a reinforcing agent, and a process for producing the conjugated diene-based polymer. There is provided a conjugated diene-based polymer having a conjugated diene unit, a monomer unit based on a compound represented by the following formula (1) and a monomer unit based on a compound represented by the following formula (2). wherein Rrepresents a hydrogen atom or a hydrocarbyl group, m is 0 or 1, Rrepresents a hydrocarbylene group, and X, Xand Xeach independently represent a substituted amino group, or a hydrocarbyl group optionally having a substituent, provided that at least one of X, Xand Xis a substituted amino group. wherein Rrepresents a hydrogen atom or a hydrocarbyl group, n is 0 or 1, Rrepresents a hydrocarbylene group, and A represents a substituted amino group, or a nitrogen-containing heterocyclic group.
