Abstract

Se dan a conocer copolímeros de etileno que tienen una relación de flujo de fusión relativamente alta y un perfil multimodal en un diagrama de fraccionamiento de elución por elevación de temperatura (TREF). Los copolímeros se pueden formar en una película que tiene buenos valores de resistencia al impacto por dardo y buenas propiedades de rigidez bajo presiones disminuidas de la extrusora.
