Abstract:

Ethylene polymers having a density from 0.908 to 0.925 g/cm, a melt index from 0.5 to 3 g/10 min, a ratio of Mw/Mn from 2 to 4, a ratio of Mz/Mw from 1.6 to 2.3, a CY-a parameter from 0.45 to 0.6, and an ATREF profile characterized by a single peak at a peak ATREF temperature from 76 to 88 C., and by less than 4.5 wt. % of the polymer eluting above a temperature of 91 C. These ethylene polymers can be used to produce various articles of manufacture, such as blown and cast films with a beneficial combination of high tear resistance and low haze.
