| abstract |
The invention provides a composition comprising a blend, which comprises a high molecular weight ethylene-based polymer, and a low molecular weight ethylene- based polymer, and wherein the high molecular weight ethylene-based polymer has a density less than, or equal to, 0.955 g/cm3, and wherein the blend has a high load melt index (I2i) greater than, or equal to, 15 g/10 min, and wherein the blend has a molecular weight distribution (Mw/Mn) greater than, or equal to, 15. The invention also provides a composition comprising a blend, which comprises a high molecular weight ethylene-based polymer and a low molecular weight ethylene-based polymer, and wherein the high molecular weight ethylene-based polymer component has a density less than, or equal to, 0.945 g/cm3, and a melt index (I2) less than, or equal to, 0.1 g/10 min, and wherein the blend has a high load melt index (I2i) less than, or equal to, 15 g/10 min, and a melt index (I5) less than, or equal to 1 g/10 min, and a molecular weight distribution (Mw/Mn) greater than, or equal to, 15. Additional compositions are disclosed. |
