Abstract
Provided are ethylene copolymers with excellent impact resistance. More specifically, provided are ethylene copolymers satisfying certain correlation between the falling dart impact strength (F) or high rate impact resistant breakage energy (E) and Vicat softening point. The ethylene copolymers with improved impact properties are applicable to film, injection, compound, sheet, roto, pipe or blow molding.
