A modified conjugated diene-based polymer and a rubber composition including the same are disclosed herein. The modified conjugated diene-based polymer has excellent processability and good tensile strength and viscoelasticity. In some embodiments, a modified conjugated diene-based polymer includes a derived unit from a modifier, the modifier including three or more alkoxy groups bonded to silicon; a non-functional chain forming a silicon-carbon bond at one side of the derived unit from a modifier and including a repeating unit derived from a conjugated diene-based monomer; and a functional chain forming a silicon-carbon bond at the other side of the derived unit from a modifier and including two or more derived units from an N-functional group-containing monomer.

Modified conjugated diene-based polymer and rubber composition including the same

A modified conjugated diene-based polymer, a rubber composition including the same, and a method of making the same are disclosed herein. The modified conjugated diene-based polymer has excellent processability and good tensile strength and viscoelasticity. In some embodiments, a modified conjugated diene-based polymer includes a first chain including a repeating unit derived from a conjugated diene-based monomer, a second chain including a repeating unit derived from a compound represented by Formula 1, and a derived unit from an alkoxysilane-based modifier, wherein the first chain and the second chain are coupled by the derived unit from the alkoxysilane-based modifier.
