PROPYLENE-BASED ELASTOMER |
| 摘要 |
Provided is a propylene-based elastomer having a narrow molecular weight distribution, a high density in the same comonomer content, and excellent mechanical properties. The propylene-based elastomer includes 50% by weight or more of a propylene-based repeating unit, and satisfies a particular relationship between an ethylene content and a molar ratio of a specific monomer sequence. |

1. A propylene-based elastomer comprising 50% by weight or more of a propylene-based repeating unit, and a residual amount of an olefin-based repeating unit comprising ethylene, wherein an ethylene content x (% by weight) and a molar ratio y (%) of propylene-propylene-ethylene sequence in the propylene-based elastomer satisfy a relationship of y≧0.75x+9.5. |
