Abstract

Se relaciona con un proceso de tres pasos para la preparación de copoliésteres que exhiben un matiz neutro, alta claridad, y brilloincrementado. El proceso involucra hacer reaccionar ácido tereftálico, etilen glicol y 1,4-ciclohexanodimetanol, en una relación molar de alimentación deglicoles totales a ácido dicarboxílico de 1,7:1 a 6,0:1, a una temperatura de 240°C a 280°C, y a una presión de 15 psig (200 kPa) a 80 psig (650 kPa), paraformar un producto de esterificación; agregarun catalizador de policondensación y un matizador; y policondensar el producto a una temperaturade 260°C a 290°C y a una presión reducida para formar un copoliéster de alto peso molecular.
