PURPOSE: An ethylene copolymer is provided to improve shock resistance and process property and to apply to a film, protrusion, compound, sheet, and hollow molding. CONSTITUTION: An ethylene copolymer is a polymerized material of alpha-olefin comonomer of C3-C18 and ethylene. The ethylene copolymer has 0.900-0.940 g/cm^3 of density and falling dart impact strength which satisfies softening point of chemical formulas 1 and 2. The alpha-olefin comonomer of C3-C18 is selected from propylene, butane, 1-pentene, 4-methyl-1-pentene, 1-hexene, 1-octene, 1-decene, 1-dodecene, and mixture thereof. |
