    Abstract: The present invention pertains to an ethylene interpolymer composition characterized as having a narrow molecular weight distribution (MWD) and optimized compositional uniformity, a process for making such a composition and a fabricated article made from such composition. The novel composition is characterized as having at least two polymer components, the first component having an ATREF peak temperature, Tpeak1 and a viscosity average molecular weight, Mv1, and the second component having an ATREF peak temperature, Tpeak2, and a viscosity average molecular, Mv2, wherein the temperature differential between Tpeak2 and Tpeak1 decreases with iincreased composition density and Mv1/Mv2 is less than or equal to 1.2. The novel composition is further characterized as having a Mw/Mn of less than or equal to 3.3 as determined by gel permeation chromatography, an I10/I2>6.6, and a composition density less than 0.945 gram/cubic centimeter. The novel composition exhibits high, balanced toughness properties, good processibility and surprisingly improved optical properties and is particularly well-suited for use in applications such as lamination films trash can liners and heavy duty shipping bags, especially as a blown film.

    Abstract: 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 100null F. (38null C.).
