Abstract:
1. An ethylene polymer having: (i) a density defined by equation (1) where ρ is a density of the polymer in g/cc, log M is a log weight average molecular weight of the polymer, a is about 1.0407 and b is about 0.0145; and (ii) a polydispersity index of greater than about 7 wherein the polymer has a density of greater than about 0.960 g/cc and displays a moisture vapor transmission rate of less than or equal to about 0.37 grams-mil per 100 square inch per day when tested in accordance with ASTM F1249 and wherein the polymer may be formed into a film at an extrusion pressure that is about 25% lower than that of a film formed from a polymer of the same molecular weight prepared using a metallocene catalyst.
