Abstract

Un proceso para el reciclaje de poliésteres, en el cual se hace reaccionar poliéster usado o de desecho con glicol para producir un monómero uoligómero de bajo peso molecular, por despolimerización del poliéster. El monómero uoligó mero, según corresponda, es entonces purificado usando uno omás de un número de pasos que incluyen la filtración, cristalización, y opcionalmente el tratamiento con adsorbente o evaporación. El monómero uoligómero así producido esparticularm ente adecuado como materia prima para la producción de poliéster a base de ácido o éster, de material de poliéster degrado de envasado. Debido a que el proceso incluye pasos de purificación, las especificaciones para el material depoliéster previ amente usado no necesitanser estrictas.
