Abstract

Se revela un método para la produccion de poliésteres mediante la policondensacion catalizada de reactivos formadores de poliéster en presenciade un catalizador de policondensacion, la mejora caracterizada porque comprende la utilizacion de titanilo xalato de litio como catalizador parauna reaccion de esterificacion o transesterificacion más rápida. El proceso mejorado produce un poliéster de superior calidad en el color en relacion a otroscatalizadores de titanil-oxalato y un novedosopoliéster que no contiene antimonio.
