Abstract

Las mezclas de poliéster de tereftalato de polietileno e isoftalato de polietileno recubiertas con un carbonato de alquileno como, por ejemplo, carbonatode etileno o carbonato de propileno se cristalizan más rápidamente y a una temperatura más baja que las de las pellas no recubiertas, lo que reduce latendencia de las pellas a adherirse durante el procedimiento de cristalizacion antes de llevar a cabo la polimerizacion en estado solido.
