Abstract
A polyethylene composition has a density of from 0.941 to 0.962 g/cm; a melt index, Iof from 0.5 to 5.0 g/10 min; a melt flow ratio, I/Iof ≥40; a Z-average molecular weight distribution, Mz/Mw of ≥2.5; a comonomer distribution breadth index, CDBIof >50 wt %; and a long chain branching factor, LCBF of >0.0010. In a temperature rising elution fractionation (CTREF) analysis, the polyethylene composition has greater than 70 weight percent of material eluting at a temperature of greater than 90° C.
