Patent ID: 8383730

Claim:
A bimodal polyethylene composition, comprising: a high molecular weight component having a weight average molecular weight (Mw) of from about 400,000 to about 950,000; a low molecular weight component having a weight average molecular weight (Mw) of from about 3,000 to about 100,000, wherein the high molecular weight component is present in an amount ranging from about 25 wt % to about 40 wt % of the bimodal polyethylene composition; and wherein the composition has a percent die swell of less than about 80% and a weight average molecular weight (Mw) of from about 200,000 to about 450,000, a z-average molecular weight (Mz) of from 2,000,000 Daltons to about 3,500,000 Daltons, and a z+1 average molecular weight (Mz+1) of from about 2,000,000 Daltons to about 6,000,000 Daltons.
