Claim 34:
35. A polymer composition comprising from 1 to 100 percent by weight of a polyethylene homopolymer composition, the polyethylene homopolymer composition comprising:
(1) 10 to 90 weight % of a first ethylene homopolymer having a density, d1 of from 0.943 to 0.975 g/cm3, a melt index, I21 of from 0.01 to 10 g/10 min, and a molecular weight distribution, Mw/Mn of less than 3.0; and
(2) 90 to 10 weight % of a second ethylene homopolymer having a density, d2 of from 0.950 to 0.985 g/cm3, a melt index, I22 of at least 500 g/10 min, and a molecular weight distribution, Mw/Mn of less than 3.0;
wherein the ratio of the melt index, I22 of the second ethylene homopolymer to the melt index, I21 of the first ethylene homopolymer is at least 50, and wherein the polyethylene homopolymer composition has a weight average molecular weight, Mw of ≤75,000, a high load melt index, I21 of at least 200 g/10 min, and a molecular weight distribution, Mw/Mn of from 4.0 to 12.0.
