Abstract

Una mezcla líquida de ácido tereftálico con un alquilenglicol apropiada como una mezcla de material de partida para una reacción de policondensación de poliéster se produce preparando una mezcla líquida de partículas de ácido tereftálico preparadas mediante la hidrólisis de un tereftalato de dialquilo con cuando menos un tipo de alquilenglicol y que tiene una temperatura de 100 a 130ºC, y luego agitar la mezcla líquida durante 15 minutos a 3 horas mientras que la temperatura de la mezcla líquida se mantiene en la escala arriba mencionada, para controlar las propiedades de suspensión de la mezcla líquida.
