Disclosed are oil-extended 1,2-polybutadiene containing an extender oil in a specific amount based on 1,2-polybutadiene and a production method thereof, and a composition further containing another (co)polymer, a foaming agent, a crosslinking agent, a softening agent and other additives. The resulting oil-extended 1,2-polybutadiene and the composition thereof has excellent functions characterizing conventional 1,2-polybutadiene and is further excellent in wear resistance, fluidity (processability), coloring properties (high distinctness of images), flexibility, attachability and the like, so that they can be applied to various formed articles, shoe sole materials and laminate having high performances. |
