PROCESS FOR PRODUCTION OF HIGH MELT FLOW PROPYLENE-BASED POLYMER AND PRODUCT FROM SAME |
| 摘要 |
<p>Disclosed are catalyst compositions having an internal electron donor which includes a 3,6-di-substituted-1,2-phenylene aromatic diester. Ziegler-Natta catalyst compositions containing the present catalyst compositions exhibit very high hydrogen response, high activity, high selectivity and produce propylene-based olefins with high melt flow rate.</p> |
