Abstract
The instant invention provides rotational molded articles, and method of making the same. The rotational molded articles according to the present invention comprise a polyethylene composition comprising: (a) at least 85 percent by weight of the units derived from ethylene; and (b) less than 15 percent by weight of units derived from one or more α-olefin comonomers; wherein the polyethylene composition has a density in the range of 0.930 to 0.945 g/cm3, a molecular weight distribution (Mw/Mn) in the range of 1.70 to 3.50, a melt index (I2) in the range of 0.5 to 20 g/10 minutes, a molecular weight distribution (Mz/Mw) in the range of less than 2.5, vinyl unsaturation of less than 0.06 vinyls per one thousand carbon atoms present in the backbone of the polyethylene composition.
