摘要： The present invention relates to elastic articles comprising a crosslinked or crosslinkable ethylene polymer and a method for making the same. In particular, the invention relates to a shaped article (e.g. film or fiber) characterized by improved elasticity at elevated temperatures and comprising a substantially cured, irradiated, or crosslinked (or curable, irradiated or crosslinkable) homogeneously branched ethylene polymer. The improved elastic article of the present invention is particularly suitable for use in applications where good elasticity must be maintained at elevated temperatures such as, for example, personal hygiene items and disposable infection-control garments at body temperatures of about 100° F. (38° C.).

摘要： The present invention relates to a method of making improved polyolefinic elastic articles from cured, irradiated or crosslinked amorphous ethylene interpolymers. In particular, the invention relates to a method of making a shaped article (e.g. film or fiber) characterized by improved elevated temperature elasticity as well as washability and dryability. The inventive elastic article comprises a substantially cured, irradiated, or crosslinked (or curable, irradiated or crosslinkable) homogeneously branched ethylene interpolymer characterized as having a density less than 0.90 g/cm3 and containing at least one nitrogen-containing stabilizer. The improved elastic article of the present invention is particularly suitable for use in applications where good elasticity must be maintained at elevated temperatures and after laundering such as, for example, elastic waist bands of undergarments and other clothing.

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.
