摘要: The present invention relates to an elastic article comprising at least one hydrogenated block polymer and, optionally, other selected from the group consisting of a reactive tailored liquid polyurethane, elastomeric or sulfonated ethylene/vinyl aromatic interpolymer, ethylene/C3 C20 .alpha.-olefin C3-C20 .alpha.-olefin/conjugated diene polypropylene polymer, enhanced thermoplastic copolyester, partially polyamide, hydroxyl functionalized polyether (or polyetheramine), styrene/conjugated and metallocene-catalyzed synthetic blend formulated system thereof. In particular, pertains shaped articles such as, for example, but not limited to, fibers, fabric, film as well composites same, especially composite absorbent item article. Inventive items include, are feminine hygiene napkins, incontinence pads, disposable diapers, training pants. term "elastic article" is used in reference items, while material" novel compositions invention.
