HIGH TEAR STRENGTH POLYMERS |
| 摘要 |
<p>Heterogeneous ethylene based hydrocarbon copolymers having high tear strength properties in film form, formed from ethylene, C3-4 monomer and C5-8 monomer with a molar ratio in the polymer of < IMG > of about 0.006 to 0.09, a < IMG > ratio of about 0.003 to 0.07 and having a Chain Branch Factor of about 0.2 to 0.8 and a narrow molecular weight distribution; a gas phase process for making such polymers, and film made from such polymers.</p> |
