Patent ID: 6953831

Claim:
An ethylene polymer, which is an ethylene homopolymer or a copolymer of ethylene with an α-olefin having a carbon number of from 3 to 20, and which satisfies the following conditions (1) to (4): (1) the melt index (HLMI) under a load of 21.6 kg at 190° C. is from 0.1 to 1,000 g/10 min, (2) the density (d) is from 0.935 to 0.985 g/cm 3 , (3) the relation between HLMI and d satisfies the following formula (i): d ≧0.00900×Log( HLMI )+0.951 (i) (4) the relation between the environmental stress cracking resistance (ESCR) and the flexural modulus (M) satisfies the following formula (ii): M ≧−7310×Log( ESCR )+32300 (ii).
