The invention relates to a polyethylene composition comprising from about 0.5 to about 20% by weight of alpha-olefin derived units other than units derived from ethylene, the remainder comprising units derived from ethylene, unsaturations. total internal (Vy1 + Vy2 + T1) from about 0.10 to about 0.40 per 1000 carbon atoms, an MI of about 0.1 to about 6 g / 10 min, an HLMI of about 5.0 at about 40 g / 10 min, a density of about 0.890 to about 0.940 g / ml, a Tw1-Tw2 value of about -25 to about -20 ° C, a Mp1 / Mp2 value of about 1.2 to about about 2.0, an Mw / Mn of about 4.5 to about 12, an Mw / Mw of about 2.0 to about 3.0, an Mz / Mn of about 7.0 to about 20, and a g (screw) greater than 0.90. |
