FIELD: chemistry.
SUBSTANCE: invention relates to a modified conjugated diene polymer, as well as a rubber composition containing this polymer. The modified conjugated diene polymer includes a unit derived from a modifier that is an amine-containing alkoxysilane compound containing three or more alkoxy groups bonded to silicon; a non-functional chain forming a silicon-carbon bond on one side of a unit derived from a modifier and including a repeating unit derived from a conjugated diene monomer; and a functional chain forming a silicon-carbon bond on the other side of a unit derived from a modifier and including two or more units derived from a monomer containing an N-functional group.
EFFECT: resulting polymer has excellent filler affinity as well as excellent processability and abrasion resistance.
