Abstract
A composition is provided, comprising (1) a narrow molecular weight distribution component having an Mw/Mn in the range of about 1.0 to about 2.0 and a weight average molecular weight in the range of about 500 to about 7,500 comprising an ethylene homopolymer; and (2) a broad molecular weight distribution component having an Mw/Mn greater than or equal to about 3.0 and a weight average molecular weight in the range of about 100,000 to about 750,000 comprising and ethylene copolymer; wherein said narrow molecular weight distribution component is present in the polymer composition in an amount of at least about 10 weight percent as based on the total weight of the polymer composition. In another embodiment, the narrow molecular weight distribution component further comprises an ethylene/hexene copolymer.
