Ethylene polymer and process for preparing the same |
摘要 |
An ethylene polymer having small values of Mw/Mn and Mz/Mw, a small proportion of long-chain branches, a high melt tension and a high swell ratio and a process for preparing the same by polymerizing ethylene in the presence of an ethylene polymerization catalyst comprising a solid titanium catalyst component containing titanium, magnesium, halogen and a compound having at least two ether linkages present through plural atoms with an organometallic compound catalyst component.
