<p><P>PROBLEM TO BE SOLVED: To provide an ethylene polymer which has excellent moldability and gives a molded product particularly having excellent mechanical strength and external appearance, especially a blow molding, a pipe and a pipe coupling. <P>SOLUTION: The ethylene polymer contains 0.01 to 1.20 mol% of a constitutional unit derived fromα-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 which are eluted at 73 to 76°C being not more than 4,000 and (2) the relation (Eq-1): S<SB>x</SB>/S<SB>total</SB>≤0.1 is satisfied. In the Eq-1, S<SB>x</SB>is the area total value of the whole peaks based on the components eluted at 70 to 85°C and S<SB>total</SB>is the area total value of the whole peaks based on the components eluted at 0 to 145°C. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
