Abstract

La invencion se refiere a un procedimiento para el tratamiento termico de pellets de poliester para lograr una cristalizacion. El tereftalato de polietileno, en lo sucesivo abreviado como PET, es un poliester con grupos de ester que se repiten. El PET puede presentarse en diversas estructuras, a saber, en forma amorfa o cristalina, o bien, parcialmente cristalina. En lo anterior, el PET amorfo es por lo general transparente; el PET cristalino, opaco o blanco. Como sucede con todos los termoplasticos que pueden presentarse en forma amorfa o cristalina, tampoco en el caso de PET es posible un grado de cristalizacion del 100%. Solo una parte de la estructura del PET puede orientarse, es decir, cristalizarse. Las zonas cristalinas y amorfas se alternan. Por ello, siempre debe hablarse de una cristalinidad parcial.
