Abstract:
Disclosed are a coupling agent for a rubber composition and a rubber composition for a tire containing the same. The rubber composition according to the present disclosure contains a coupling agent that may induce interactions between a rubber as a raw material and carbon black, thereby improving dispersibility of the carbon black in the rubber composition. Thus, a tire with low rolling-resistance and excellent wear resistance may be realized.
