Polyethylene compositions, articles thereof, and methods thereof

Abstract

The present disclosure relates to polyethylene compositions, articles including such polyethylene compositions, and methods of making polyethylene compositions and articles (e.g., films) thereof. In some embodiments, a method of making a polyethylene composition includes introducing ethylene, an optional comonomer, a diluent, a catalyst, and 30 ppm to 500 ppm of a cocatalyst to a loop reactor under conditions sufficient to produce a slurry comprising the polyethylene composition. The method includes continuously discharging a portion of the slurry from the loop reactor as effluent comprising the polyethylene composition. The method includes flashing the effluent to vaporize diluent and form a concentrated effluent comprising the polyethylene composition. The method includes condensing the vaporized diluent. The polyethylene composition comprises 80 wt % or greater ethylene-derived units and has a density within the range from 0.935 to 0.975 g/cm; and a melt index (I) of 2 g/10 min to 4 g/10 min.
