Title
(EN) HIGH-DENSITY POLYETHYLENE COMPOSITIONS AND METHOD OF MAKING THE SAME
Abstract
(EN)
The instant invention is a high-density polyethylene composition, method of making the same, and articles made therefrom. The high-density polyethylene composition of the instant invention includes an ethylene alpha-olefin copolymer having a density in the range of 0.935 to 0.952 g/cm ┬ęKIPO&WIPO 2009
