Claims44
A composition comprising an ethylene polymer having a polydispersity (Mw/Mn) greater than about 40, a high load melt index (HLMI) from about 5 to about 15 grams per ten minutes, a shear ratio (HLMI/MI) greater than about 400, and a density from 0.945 to 0.955 grams per cubic centimeter, wherein the ethylene polymer is an ethylene homopolymer or a copolymer of ethylene and an α-olefin having from 4 to about 16 carbon atoms per molecule.
A composition comprising an ethylene polymer having a high load melt index (HLMI) from about 2 to about 20 grams per ten minutes, a shear ratio (HLMI/MI) greater than about 400, and a density from 0.945 to 0.955 grams per cubic centimeter, wherein the ethylene polymer is an ethylene homopolymer or a copolymer of ethylene and an olefin having from 4 to about 16 carbon atoms per molecule.
A composition comprising an ethylene polymer having a density from 0.945 to 0.955 grams per cubic centimeter, a shear ratio (HLMI/MI) greater than about 300, a high load melt index (HLMI) from about 2 to about 20 grams per ten minutes, and a pent test greater than about 500, wherein the ethylene polymer is an ethylene homopolymer or a copolymer of ethylene and an olefin having from 4 to about 16 carbon atoms per molecule.
