ETHYLENE POLYMER, CATALYST FOR PRODUCTION OF ETHYLENE POLYMER, AND PROCESS FOR PRODUCTION OF ETHYLENE POLYMER

摘要

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 C 3-8 ±-olefin, the ethylene polymer being satisfied with the following (A) to (F).
(A) Density (d (kg/m 3 )) 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 (MS 160 (mN)) measured at 160°C and MFR are satisfied with MS 160 >90-130×log(MFR), (E) melt strength (MS 190 (mN) ) measured at 190°C and MS 160 are satisfied with MS 160 /MS 190 <1.8, and (F) fluidized activation energy (E a (kJ/mol) ) and d are satisfied with 127-0.107d
