Abstract
La presente invención revela composiciones de polímero llenado teniendo una microestructura porosa única y respirabilidad mejorada. En una realización, la composición de la presente invención se puede desechar en el inodoro y comprende un polímero sensible al agua de óxido de etileno y compuesto de arcilla no modificada o silicato estratificado. Las composiciones de la presente invención son útiles para fabricar películas, fibras y artículos respirables y que se pueden desechar en el inodoro. De manera conveniente, las películas, fibras y articulos respirables de la presente invención pueden formarse de una manera económica y eficiente sin la formación de espuma y estiramiento.The present invention discloses filled polymer compositions having a unique porous microstructure and improved breathability. In one embodiment, the composition of the present invention can be flushed down the toilet and comprises a water sensitive polymer of ethylene oxide and an unmodified clay or layered silicate compound. The compositions of the present invention are useful for making films, fibers, and items that are breathable and can be flushed down the toilet. Conveniently, the breathable films, fibers, and articles of the present invention can be formed inexpensively and efficiently without foaming and stretching.
