Abstract

Un proceso de solución de reactor dual proporciona composiciones de polietileno de alta densidad que contienen un primer copolímero de etileno y un segundo copolímero de etileno y que tienen buena procesabilidad, tenacidad y resistencia al agrietamiento por tensión ambiental. Las composiciones de polietileno son adecuadas para la preparación de partes rotomoldeadas.
