Disclosed are oil-extended 1,2-polybutadiene containingnan extender oil in a specific amount based on 1, 2-polybutadienenand a production method thereof, and a composition furtherncontaining another (co)polymer, a foaming agent, a crosslinkingnagent, a softening agent and other additives. The resultingnoil-extended 1,2-polybutadiene and the composition thereof hasnexcellent functions characterizing conventional 1,2-polybutadienenand is further excellent in wear resistance, fluidityn(processability), coloring properties (high distinctness ofnimages), flexibility, attachability and the like, so that theyncan be applied to various formed articles, shoe sole materialsnand laminate having high performances. |
