Abstract
Se refiere a un procedimiento para la cristalizacion de un prepolímero de PEN que contiene componentes volátiles. La temperatura se mantiene a unatemperatura ubicada en un rango comprendido entre aproximadamente 20°C más que la Tg yaproximadament e 10°C menos que el Tm, mientras el polímero de PEN seagita. El prepolímero de PEN está presente como astillas o pellets. La presion durante la cristalizacion se mantiene a un nivel mayor que la presion de vaporde los componentesvolátiles en las as tillas o en los pellets del prepolímero de PEN, convenientemente mediante la presencia de un gas y/o un líquido o unamezcla de líquidos. Se refiere además a un procedimiento para preparar un poliéster de alto pesomolecular.
