Abstract

Las composiciones de poliéster cristalizable que contienen un nucleador de cristalizacion de poliamida alifática exhiben velocidades de cristalizacion controlables y ajustables al enfriarse después de la fusion y son termoformables en los procesos de fundir-para-moldear. Reivindicacion 1: Un proceso para la fabricacion por fundido-moldeado de recipientes de poliéster cristalizado por el cual un film de composicion de poliéster cristalizable por lo menos parcialmente fundido es formado y el film es termoformado y cristalizado por enfriamiento a una temperatura entre el Tg del poliéster y el Tm del poliéster, cuya mejora comprende aumentar la velocidad de cristalizacion, al agregarle a dicho poliéster cristalizable con anterioridad a la formacion del film del mismo, una cantidad de un nucleador de cristalizacion de poliamida alifática efectiva para aumentar la velocidad de cristalizacion de dicho poliéster cristalizable.
