Beschreibung
Zusammenfassung:The present invention provides an ethylene polymer that has excellent fluidity and moldability as well as gives a molded product having excellent mechanical strength. The ethylene polymer of the present invention contains 0. 02 to 1. 50 mol% of a constitutional unit derived from ±-olefin having 6 to 10 carbon atoms, and has the density of 945 to 975 kg/m 3 which satisfies both of the following requirements [1] and [2] simultaneously: [1] in CFC, all the components having a molecular weight of 100, 000 or more are eluted at a temperature of 85 C or higher; and [2] the components eluted at a temperature of 80 C or lower account for up to 5% of all the components eluted in CFC.
