| description | The present invention relates to an ethylene/1-hexene or ethylene/1-butene copolymer having excellent processibility. The ethylene/1-hexene or ethylene/1-butene copolymer according to the present invention has excellent processibility by having high molecular weight and wide molecular weight distribution, and can be applied to a heating tube with high internal pressure, a mining pipe or a large diameter pipe by means of excellent environmental stress crack resistance. The ethylene/1-hexene or ethylene/1-butene copolymer has weight average molecular weight (g/mol) of 10,000 to 400,000, molecular weight distribution (Mw/Mn, PDI) of 2 to 30, and environmental stress crack resistance (ESCR) of 400 to 20,000 hours, wherein the environmental stress crack is measured by a full notch creep test at 4.0 MPa and 80°C according to ISO 16770.
본 발명은 가공성이 우수한 에틸렌/1-헥센 또는 에틸렌/1-부텐 공중합체에 관한 것이다. 본 발명에 따른 에틸렌/1-헥센 또는 에틸렌/1-부텐 공중합체는 고분자량 및 넓은 분자량 분포를 가져 가공성이 우수하고, 환경 응력 균열 저항성이 우수하여 고내압 난방관, mining 파이프 또는 대구경 파이프 등에 적용할 수 있다. |
