Zusammenfassung:	Provided is a polybutadiene that has improved processability and improved wear resistance. The polybutadiene satisfies the following requirements: (A) having a Mooney viscosity (ML1+4, 100 DEG C) of 43 or greater; (B) showing a ratio (Tcp/ML1+4, 100 DEG C) of 5 wt% toluene solution viscosity (Tcp) to Mooney viscosity (ML1+4, 100 DEG C) of 0.9-2.3; (C) having a stress relaxation time (T80) of 10.0-40.0 seconds, said T80 being defined as, by referring the torque at the termination of the (ML1+4, 100 DEG C) measurement to 100%, the time required for the torque to decrease to 80%; and (D) showing a molecular weight distribution (Mw/Mn) of 2.50-4.00.
