    • 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/cm 3 . 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 0 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/cm 3 ; (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 0 C. according to ASTM D-6290. Articles according to instant invention comprises the above- described inventive high-density polyethylene composition.
    • 本发明是一种高密度聚乙烯组合物,其制造方法,由其制造的制品以及制造这种制品的方法。 根据本发明的高密度聚乙烯组合物包含第一组分,第二组分和第三组分。 第一组分是密度为0.940-0.980g / cm 3的高密度聚乙烯聚合物。 第二组分是聚乙二醇,第三组分是十八烷基3-(3,5-二叔丁基-4-羟基苯基)丙酸酯。 本发明的高密度聚乙烯组合物在100°C加速老化0小时时的黄度指数小于约-2.5。 根据ASTM D-6290。 本发明制备高密度聚乙烯组合物的方法包括以下步骤:(1)提供第一组分,其中第一组分为密度范围为0.940-0.980g / cm 3的高密度聚乙烯聚合物, 厘米 3 ; (2)提供第二组分,其中第二组分是聚乙二醇; (3)提供第三组分,其中第三组分是3-(3,5-二叔丁基-4-羟基苯基)丙酸十八烷基酯; (4)将第二和第三组分混合到第一组分中,从而形成混合物; (5)将混合物造粒; 和(6),由此在100℃加速老化0小时时形成黄度指数小于约-2.5的高密度聚乙烯组合物的粒料。 根据ASTM D-6290。 根据本发明的制品包含上述本发明的高密度聚乙烯组合物。
