| 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 are disclosed. A process for preparing an ethylene polymer 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 is further disclosed. Therefore, the ethylene polymer is excellent in moldability, and from this polymer, a molded article which is excellent in rigidity and impact resistance and free from poor appearance can be obtained.
