Patent ID: 7825190

Claim:
A polyethylene composition comprising a low-molecular-weight (LMW) ethylene homopolymer component with a M w /M n less than 8, and a high-molecular-weight (HMW) ethylene interpolymer component with a M w /M n of 3 or less, and wherein the polyethylene composition has a bimodal molecular weight distribution, and a molecular weight distribution, as defined by the ratio of M w /M n , of about 30 or less, a density greater than, or equal to, 0.94 g/cm 3 , and has a melt index, I5, less than, or equal to, 0.5 g/10 min and an I21/I5 ratio less than 22.5, and wherein the high molecular weight component has a reverse comonomer distribution.
