Abstract

Se describen composiciones de polímero de etileno que contienen un primer componente de polímero de etileno ramificado homogéneamente y 15-35 % en peso de un segundo componente de polímero de etileno ramificado homogéneamente de mayor densidad que el primer componente de polímero de etileno. La composición de polímero de etileno puede caracterizarse por una densidad de 0.912 a 0.925 g/cm3, un cociente de Mw/Mn de 2 a 5, un índice de fluidez menor que 2 g/10 min y un parámetro CY-a a 190 °C de 0.35 a 0.7. Estas composiciones de polímero tienen la resistencia al impacto de dardo y las propiedades ópticas excelentes de un LLDPE catalizado con metaloceno, pero con resistencia al desgarro en la dirección de la máquina mejorada, y se pueden usar en película soplada y otras aplicaciones de uso final. Además, también se describen métodos para mejorar la resistencia al desgarro Elmendorf de la película.
