Abstract

El nylon-6 es utilizado para la fabricacion de fibras, películas y productos moldeados. Los polímeros obtenidos mediante la polimerizacion en fusioncomprenden un elevado nivel de epsilon-caprolactama y de productos de reaccion de bajo peso molecular(oligomero) a causa de los equilibrios químicos. Dado queel oligomero de caprolactama y el monomero de caprolactama son solubles y pueden ser extraídos en agua, el nivel de constituyentes de bajo peso molecular en elpolímero también es conocido comosu contenido de extraíbles. Para evitar todo deterioro en la calidad del producto y las propiedades de procesamiento, porejemplo durante el moldeo por inyeccion o extrusion o durante el hilado, el contenido de extraíbles debe ser disminuído.
