Process for olefin polymerization |
摘要 |
Olefins are polymerized with a catalyst composition which forms on mixing a supported chromium oxide catalyst system and a silane compound. This composition allows the production of one or more comonomers in-situ. The resultant polymer has a lower density, a higher melt index, and a higher high load melt index than polyers produced with a similar catalyst system in the absence of a silane compound. |
