Abstract

Un método para el tratamiento de poliéster que comprende:(a) la combinación del poliéster con una composición alcalina para revestir por lo menos una porción del poliéster; y(b) el calentamiento de la mezcla a una temperatura que no es mayor del punto de fusión del poliéster caracterizado porque la etapa (b) es realizada en un medio ambiente que contiene no más de 80 ppm de agua.Un método para la recuperación de poliésteres que contienen contaminantes y/o impurezas que comprende:(a) la mezcla de los materiales que contienen poliéster con una composición alcalina, cuya composición alcalina es empleada para reaccionar con una porción del poliéster en el material que contiene poliéster; y(b) el calentamiento de la mezcla a una temperatura efectiva para saponificar una porción del poliéster pero insuficiente para fundir el poliéster,(c) la separación de por lo menos una porción del poliéster de los materiales remanentes, caracterizado porque la etapa (b) es realizada en un medio ambiente que contiene no más de 80 ppm de agua.
