Abstract

La invención se refiere a un procedimiento para la producción de un polímero semi-cristalino, la cual consiste de los siguientes etapas: producir un polímero fundido a partir de un polímero cristalizable; moldear las partículas y solidificar el polímero fundido, en donde la formación de las partículas puede realizarse antes o después de la solidificación; enfriar las partículas; tratar las partículas para reducir su tendencia a aglomerarse; cristalización de las partículas. De acuerdo con la invención el tratamiento se realiza por agitación a una temperatura T1, que se encuentra por debajo de la temperatura de transición cristalina del polímero más 10°C, o sea Tl<Tg + 10°C.
