ABSTRACT:
An object of the present invention relates to provide an ethylene polymer having excellent mechanical strength and excellent molding processability in a wide molding processing temperature range. The invention relates to use an ethylene polymer comprising a repeating unit derived from ethylene, or a repeating unit derived from ethylene and a repeating unit derived from a C3-8α-olefin, the ethylene polymer being satisfied with the following (A) to (F). (A) Density (d (kg/m3)) is from 910 to 970, (B) MFR (g/10 min)) is from 0.01 to 50, (C) terminal vinyl number is 0.2 or less per 1,000 carbon atoms, (D) melt strength (MS160(mN)) measured at 160° C. and MFR are satisfied with MS160>90−130×log(MFR), (E) melt strength (MS190(mN)) measured at 190° C. and MS160are satisfied with MS160/MS190<1.8, and (F) fluidized activation energy (Ea(kJ/mol)) and d are satisfied with 127−0.107d<Ea<88−0.060d.
