<p><P>PROBLEM TO BE SOLVED: To provide an ethylene-based polymer excellent in moldability, and mechanical strength and environmental breaking stress resistance, and giving a molded article excellent in appearance, especially a blow-molded article. <P>SOLUTION: This ethylene-based polymer containing 0.02-0.50 mol% constituting unit derived from a 6-10Cα-olefin is provided by satisfying any one of the following (1) and (2) in its cross fractionation chromatography (CFC). (1) The amount of eluted components at≤80°C is≤5% based on the total eluted amount in the CFC. (2) A relational formula (Eq-1): S<SB>x</SB>/S<SB>total</SB>≤0.1 [wherein, S<SB>x</SB>is the total value of areas of total peaks based on the components eluted between 70-85°C; S<SB>total</SB>is the total value of areas of total peaks based on the components eluted between 0-145°C] is satisfied. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
