Abstract

Terpoliésteres poli(etilentereftalato-co-etilenisoftalato-co- etilen-5-tert-butil-isoftalato). Los terpoliésteres obtenidos por policondensación en masa a partir de etilenglicol con mezclas de dimetil tereftalato, dimetil isoftalato y ácido 5-tert-butil- isoftálico con una proporción total de unidades etilen isoftalato y etilen 5-tert-butil isoftalato entre un 2 y un 40 mol % y de unidades etilen tereftalato entre un 98 y un 60 mol %, son polímeros que presentan mayor dificultad en cristalizar que el poli(etilentereftalato) y que los copoliésteres de etilen tereftalato y etilen isoftalato con un mismo contenido en unidades de etilen tereftalato. Estos terpolímeros tienen temperaturas de transición vítrea superiores o inferiores al poli(etilentereftalato) dependiendo de la composición y temperaturas de fusión siempre inferiores al poli(etilentereftalato). Los terpoliésteres que contienen menos del 80 mol % de etilen tereftalato son amorfos. Las temperaturas de descomposición de todos los terpoliésteres son superiores a 400 °C. La temperatura de fusión, menor que la del poli(etilentereftalato), permite un procesado más cómodo y económico a temperaturas inferiores y la menor velocidad de cristalización permite la fabricación de piezas, envases y objetos transparentes y de mayor espesor.
