| 摘要 |
The invention provides a composition comprising a first composition, wherein the first composition comprises a first ethylene-based polymer and a second ethylene-based polymer, and wherein the first composition has a high load melt index (I21) less than 17, a density greater than, or equal to, 0.952 g/cm3, a molecular weight distribution MWD (conv), defined as the ratio of the weight average molecular weight to the number average molecular weight (Mw(conv)/Mn(conv)), greater than, or equal to, 11; and a viscosity ratio, &eegr;(0.01 s−1)/&eegr;(100 s−1) at 190° C., greater than, or equal to, 60. |
