    摘要： The instant invention is a high-density polyethylene composition, method of producing the same, articles made therefrom, and method of making such articles. The high-density polyethylene composition according to instant invention includes a first component, a second component, and a third component. The first component is a high-density polyethylene polymer having a density in the range of 0.940 to 0.980 g/cm3. The second component is polyethylene glycol, and the third component is octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate. The high-density polyethylene composition of the instant invention has a Yellowness Index of less than about −2.5 at 0 hour of accelerated aging at 100° C. according to ASTM D-6290. The process for producing the high-density polyethylene composition according to instant invention includes the following steps: (1) providing a first component, wherein the first component is a high-density polyethylene polymer having a density in the range of 0.940 to 0.980 g/cm3; (2) providing a second component, wherein the second component is polyethylene glycol; (3) providing a third component, wherein the third component is octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate; (4) blending the second and third components into the first component thereby forming a blend; (5) pelletizing the blend; and (6) thereby forming pellets of the high-density polyethylene composition having a Yellowness Index of less than about −2.5 at 0 hour of accelerated aging at 100° C. according to ASTM D-6290. Articles according to instant invention comprises the above-described inventive high-density polyethylene composition.
