Abstract

Un método para el tratamiento de poliésteres comprende la combinacion de partículas discretas de un poliéster con una composicion alcalina de modo que lacomposicion alcalina reviste las partículas de poliéster. Las partículas son luego calentadas enun medio ambiente que está por lo menos substancialmente librede agua. El método puede ser utilizado de manera efectiva en la limpieza, descontaminacion e incluso el incremento de la viscosidad intrínseca de losmateriales de poliéster. Además,cuando se utiliza en la recuperacion de materiales de poliéster que contienen contaminantes y/o impurezas, el método puedeproveer u producto de poliéster superior tanto en términos de viscosidad intrínseca como de color.
