(57) [Summary] (Modifications) [Problem] To provide an ethylene-based polymer in which mechanical properties and processability are balanced at a higher level than conventional ethylene-based polymers. SOLUTION: (1) density, (2) melt flow rate value (MFR), (3) Mw / Mn ratio by GPC, (4) Melt flow rate ratio (MIR), (5) Elution amount Y, (6) Elution temperature (Ti / ° C.) and GPC maximum molecular weight of elution component at the elution temperature, (7) Melt tension (MT / g) Satisfies the prescribed conditions, ethylene and C 3-20 An ethylene polymer which is a copolymer with an α-olefin, and polymerized by a Bessel type slurry polymerization method using a supported geometry-constrained single-site catalyst and the average of the polymerization slurry in one reactor The ethylene polymer obtained by a polymerization method having a residence time of 1 hour to 8 hours. |
