Abstract
Se describe un metodo para procesar un policondensado para dar un granulado comprendido de pelotillas, por medio del cual el policondensado se funde en el transcurso del metodo y luego se re-solidifica mas tarde. Dicho metodo esta caracterizado porque el tiempo total durante el cual la temperatura del policondensado esta por arriba del punto de fusion del mismo, es menos de aproximadamente 60 segundos. Dicho metodo preferiblemente se lleva a cabo por medio de una extrusora de ejes multiples, por medio de la cual la desgasificacion y/o secado del policondensado en el estado solido, ocurre a una presion por debajo de la presion atmosferica y/o con la adicion de un gas inerte. El periodo de tiempo, durante el cual el policondensado reside en la extrusora, despues de fundirse en el mismo, asciende a menos de aproximadamente 15 segundos.
