The present invention relates to a polyethylene copolymer which has excellent processability and long-term durability, and thus is useful for hollow molding of a pipe or the like.

Polyethylene copolymer and method for preparing same

An olefin polymer capable of simultaneously satisfying excellent drop impact strength and transparency, a preparation method of the same, and a film using the same, can be provided. In an embodiment, an olefin polymer comprises a plurality of polymer chains, and satisfies the following conditions: i) each polymer chain of the plurality having an average number of short chain branches (SCBs) per 1000 carbon atoms of 20/1000C or more, wherein an SCB has C2 to C7 carbon atoms, ii) a molded film of the olefin polymer having a drop impact strength of 1500 g to 2400 g as measured in accordance with ASTM D1709A, wherein the molded film having a thickness of 100 &#x3bc;m, and iii) a molded film of the olefin polymer having a haze is 10% to 30% as measured in accordance with ASTM D1003, wherein the molded film having a thickness of 0.05 mm.
