Abstract

Se trata de un interpolímero de etileno resistente, configurado, curado, irradiado o degradado por union intermolecular (crosslinked) y un artículoelástico resistente al calor que comprenden por lo menos un interpolímero de etileno y un método parap reparar dicho artículo elástico. En particular, lapresente se refiere a un artículo configurado (por ejemplo, película o fibra) caracterizado por la mejorada elasticidad a elevadas temperaturas y que comprendeun polímero de etileno sustancialmentecu rado, irradiado o degradado por union intermolecular y ramificado en forma homogénea. El artículo elástico de lapresente es particularmente adecuado para uso en aplicaciones en donde debe mantenerse la buena elasticidad a temperaturas elevadas,tal c omo, por ejemplo,artículos para la higiene personal y prendas de control de infeccion descartables a temperaturas del cuerpo de alrededor de 38*C. El interpolímero de etilenoresistente al calor, configurado, curado, irradiado o degradadocomprende et ileno interpolimerizado con por lo menos otro monomero y se caracteriza por tener(a) una densidad de polímero de menos de 0,89 g/cm3 o una cristalinidad DSC a 23*C, segun se determina utilizando calorimetría de exploracion diferencial,demenos del 26 % antes de ser configurado, curado, irradiado o degradado y (b) en forma de fibra hilada por fusion (meltspun), un valor de menos de 0,75 para laexpresion: Abs[deltaE/E0] + Abs[deltaT/T0]. En donde deltaE y deltaT se toman de ungráfico de fatiga-ten sion, segun se determina utilizando un tensiometroInstron a 500 mm/minuto de velocidad de cruceta y 10,2 cm de longitud de calibre y del promedio de cuatro repetaciones de cinco muestras de fibras; deltaE setoma como ladiferencia en porcentaje de el ongacion entre el polímero curado, irradiado o degradado y el interpolímero sin curar, irradiar o degradar a unatenacidad de 0,4 gramos/denier; E0 se toma como el porcentaje de elongacion del interpolímero no curado,no irradiado o no degradado a una tenacidad de 0,4gramos/denier; deltaT se toma como la diferencia en tenacidad (en gramos/denier) entre el polímero curado, irradiado o degradado y el interpolímero no curado,
