Abstract

Un procedimiento en dos etapas para la producción de poliésteres lineales sintéticos mediante una reacción de esterificación de un glicol y un ácido dicarboxílico, caracterizado por introducir una alimentación de un éster glicólico de un ácido dicarboxílico en la segunda etapa, presentando la citada alimentación un grado medio de polimerización superior a 1 y un grado de esterificación tal que menos del 30% en moles de los grupos terminales ácidos están sin reaccionar; mantener la suma de las presiones parciales de vapor del glicol y del agua en la segunda etapa citada en un valor inferior a 740 torr y mantener una fase de glicol líquido en dicha etapa de esterificación secundaria.
