Abstract
The present invention provides 1,4-cis polybutadiene having high linearity with an −S/R value of 1 or greater at 100° C., and accordingly, is capable of reducing resistance properties, particularly rolling resistance, and greatly enhancing fuel efficiency properties when used in a rubber composition.
