Abstract
Embodiments are directed towards polyolefin compositions including a high molecular weight polyolefin and a low molecular weight polyolefin.
Claims2
A polyolefin composition comprising:
- a high molecular weight polyolefin;
- and
- a low molecular weight polyolefin,
- wherein the polyolefin composition has a high molecular weight split of from 39 to 49 percent, a density from 0.930 to 0.970 g/cm3, a Mw/Mn greater than 17, a melt index (I21) from 15 to 40 g/10 min, and
- provides a G′/G″ (0.02 s−1) value that is greater than 0.3087+0.00404*(Eta at 0.02 s−1)/(Eta at 200 s−1)−0.224*HMW Split, and
- a G′ (G″=3000 Pa) value from 1650 to 1870 Pa.
