Abstract
A polyethylene homopolymer composition comprises: a first ethylene homopolymer having a density, dof from 0.943 to 0.975 g/cm, a melt index, Iof from 0.01 to 10 g/10 min, and a molecular weight distribution, Mw/Mn of less than 3.0; and a second ethylene homopolymer having a density, dof from 0.950 to 0.985 g/cm, a melt index, Iof at least 500 g/10 min, and a molecular weight distribution, M/Mof less than 3.0; wherein the ratio of the melt index, Iof the second ethylene homopolymer to the melt index, Iof the first ethylene homopolymer is at least 50. The polyethylene homopolymer compositions which may be nucleated have a weight average molecular weight, Mof ≤75,000, a high load melt index, Iof at least 200 g/10 min, a molecular weight distribution, M/Mof from 4.0 to 12.0 and may be usefully employed in molding applications, such as, for example, in compression molded closures.
