Patent ID: 8129472

Claim:
A composition consisting of a high molecular weight component and a low molecular weight component and at least one additive, and wherein the high molecular weight component is an ethylene interpolymer that has a density from greater than 0.930 g/cm 3 to 0.950 g/cm 3 , and an I 21 from 0.05 to 1 dg/min, and wherein the low molecular weight component is an ethylene polymer that has density from 0.965 g/cm 3 to 0.985 g/cm 3 , and an I 2 greater than 600 to 2000 dg/min, and wherein the composition has a density from 0.950 g/cm 3 to 0.970 g/cm 3 and an I 21 less than 10 dg/min, and comprises from 50 to 75 weight percent of the high molecular component, and comprises from 50 to 25 weight percent of the low molecular weight component, and wherein the weight percentages are based on the sum weight of the high molecular weight component and the low molecular weight component.
