Catalysts and polymerizations for improved polyolefins

Abstract

The present disclosure relates to polyethylene polymers and films made therefrom. In some embodiments, a polyethylene copolymer includes 90 wt% or greater of ethylene units and a remainder balance of C3-C20 comonomer units. The polyethylene copolymer has a bimodal composition distribution, a density of 0.914 g / cm 3 to 0.925 g / cm3, a melt index of 0.1 g / 10min to 1 g / 10min, a high load melt index (HLMI) of 21 g / 10 min to 70 g / 10 min, a melt index ratio (MIR) of 40 to 65, and a molecular weight distribution (MWD) of 4 to 7.
