Zusammenfassung:	The pipe articles with excellent stress crack resistance can be achieved by providing ethylene copolymer composition comprises ethylene and a C6-C10 α-olefin comonomer; the ethylene copolymer having a total density of 0.945-0.980 g/cm3 and a MFR5 of 0.10-0.50 g/10 min; and the ethylene copolymer having a comonomer content of 1-5% wt. The ethylene copolymer has Mx/My in the range of not less than 14.0; gpcBR in the range of from 0.20 to 0.80; and strain hardening modulus in the range of not less than 53.4.
