Patent ID: 7700708

Claim:
An ethylene polymer containing 0.02 to 0.5 mol % of a constitutional unit derived from α-olefin having 6 to 10 carbon atoms, which satisfies at least either of the following requirements (1) and (2) with respect to cross fractionation chromatography (CFC): (1) the weight average molecular weight (Mw) of the components eluted at 73 to 76° C. does not exceed 4,000; and (2) the following relationship (Eq-1) is satisfied: S x /S total ≦0.1 (Eq-1) wherein S x is the sum of the total peak areas related to the components which are eluted at 70 to 85° C., and S total is the sum of the total peak areas related to the components which are eluted at 0 to 145° C.
