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. A conjugated diene-based polymer obtained by reacting one end of a polymer having a monomer unit based on a conjugated diene, 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) with an alkoxysilane compound.V—S  (1)wherein Vrepresents a hydrocarbyl group having a polymerizable carbon-carbon double bond, and Srepresents a substituted silyl group.V-A  (2)wherein Vrepresents a hydrocarbyl group having a polymerizable carbon-carbon double bond, and Arepresents a substituted amino group, or a nitrogen-containing heterocyclic group.
