Abstract
La presente invención se refiere a procedimiento para la preparación de copolímeros de etileno y buteno-1, con un valor de densidad del orden de 0.880 hata aproximadamente 0.914 g/ml, por copolimerización de etileno y buteno-1, a alta temperatura y alta presión, en un reactor de tipo recipiente o tubular, en la presencia de un catalizador Ziegler, caracterizado porque el reactor se alimenta una mezcla gaseosa, que contiene etileno y buteno-1, en una relación ponderal de 15/85 a 35/65 y eventualmente hidrógeno, en una cantidad de 0 a 2,000 partes en volumen, por cada millón de partes en volumen de la mezcla.
