METHOD OF OBTAINING A PROPYLENE POLYMER MODIFIED BY MEANS OF DIENES |
| 摘要 |
The invention is concerned with a diene modified isotactic propylene polymer having a Melt Flow rate of from 0.03 to 100 dg/min and a Mw/Mn of from 2.1 to 30 comprising propylene units, from about 0.00005 to about 5 mole percent of alpha-omega-diene units and wherein the polymer is essentially gel free as defined herein and is prepared using a metallocene catalyst system. <IMAGE> |
