Abstract
Un proceso novedoso para la cristalización de poli(etilennaftalen- dicarboxilato)(PEN) y sus copolímeros. El proceso comprende la etapa demantener la cantidad de agua en dicho poli(etilennaftalendicarboxilato) por debajo de un techo de contenido de humedad crítico de aproximadamente 4200 ppmdurante todo el proceso de modo tal que no se requiere una etapa separada de secado.El proceso además comprende formar pellets de PEN, mantener el contenidoagua por debajo de 4200 ppm y cristalizar el PEN por calentamiento rápido.
