Patent

CA 2332139

The present invention relates to heat resistance elastic articles comprising a cured, irradiated, or crosslinked or ethylene polymer and a method for making the same. In particular, the invention relates to a shaped article (for example, film or fiber) characterized by improved elasticity at elevated temperatures and comprising a substantially cured, irradiated, or crosslinked 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).

La présente invention concerne des articles élastiques thermorésistants qui renferment un polymère d'éthylène durci, irradié ou réticulé, et leur procédé de fabrication. Plus particulièrement, cette invention s'applique à un article façonné (par exemple un film ou une fibre) qui se caractérise par une élasticité supérieure à chaud et qui renferme un polymère d'éthylène à chaîne ramifiée homogène, sensiblement durci, irradié ou réticulé. L'article élastique amélioré selon la présente invention convient particulièrement bien pour des applications nécessitant le maintien d'une bonne élasticité à chaud tels que des articles d'hygiène personnelle et des pièces de vêtement aseptisées jetables à des températures corporelles d'environ 100 DEG F (38 DEG C).
