摘要：
An ethylene polymer containing 0.01 to 1.20 mol % of a constitutional unit derived from α-olefin having 6 to 10 carbon atoms, wherein with respect to cross fractionation chromatography (CFC), either (1) the weight average molecular weight (Mw) of the components eluted at 73 to 76° C. does not exceed 4,000, or (2) the ethylene polymer satisfies the following relationship (Eq-1), provides a molded product having excellent moldability and therefore excellent mechanical strength and appearance: Sx/Stotal≦0.1 (Eq-1) wherein Sx is the sum of the total peak areas related to the components eluted at 70 to 85° C., and Stotal is the sum of the total peak areas related to the components eluted at 0 to 145° C.
