Abstract:
The instant invention is a polyethylene composition, method of producing the same, articles made therefrom, and method of making the same. The polyethylene composition according to the instant invention comprises (1) less than or equal to 100 percent by weight of the units derived from ethylene; and (2) less than 15 percent by weight of units derived from one or more α-olefin comonomers. The polyethylene composition according the instant invention has a density of equal to D g/cm3, wherein D=[(0.0034(Ln(I2))+0.9553], wherein I2 is melt index expressed in g/10 min, a molecular weight distribution (Mw/Mn) in the range of 1.70 to 3.62, a melt index (I2) in the range of 2 to 1000 g/10 minutes, a molecular weight distribution (Mz/Mw) in the range of less than 2.5, and a vinyl unsaturation of less than 0.06 vinyls per one thousand carbon atoms present in the backbone of the composition.
