A polyethylene composition which has a wide molecular weight distribution and excellent balance among melt elasticity, flow characteristics and mechanical properties, and which is suitable for use in producing large-scaled hollow plastics articles. The composition comprises a higher molecular weight ethylene polymer or copolymer and a lower molecular weight ethylene polymer or copolymer which is specified in view of the content of o-dichlorobenzene and the ratio of the area under the elution temperature-eluate volume curve between 25 DEG to 90 DEG C. to the area under said curve of 90 DEG C. and above in temperature rising elution fractionation. |
