Abstract: In various embodiments, a bimodal polyethylene may include a high molecular weight component and a low molecular weight component. The bimodal polyethylene may have a density of from 0.933 g/cm3 to 0.960 g/cm3, a melt index (I2) of from 0.3 dg/min to 1.2 dg/min, and a melt flow ratio (MFR21) greater than 70.0. The high molecular weight component may have a density of from 0.917 g/cm3 to 0.929 g/cm3, and a high load melt index (I21) of from 0.85 dg/min to 4.00 dg/min. The bimodal polyethylene may include from 40 wt. % to 60 wt % of the high molecular weight component. Methods for producing the bimodal polyethylene and articles manufactured from the bimodal polyethylene are also provided.

Abstract: A polymeric composition includes a resin including an ethylene-based polymer and a copolymer of ethylene and an alpha olefin comonomer. The resin has a High Mw Comonomer Content of 3.2 wt % or greater based on a total weight of the resin over the weight average molecular weight range of 105 g/mol to 105.5 g/mol as measured by Ethylene GPC. The polymeric composition has a Relevant Comonomer Content of 0.6 wt % or greater. The polymeric composition also includes at least one of (i) a polydimethylsiloxane having a weight average molecular weight of 550,000 g/mol to 650,000 g/mol as measured according to Component GPC and (ii) a polymeric ultraviolet light stabilizer comprising a hindered amine moiety and having a weight average molecular weight from 5,000 g/mol to 20,000 g/mol as measured according to Component GPC.
