Abstract
Polímeros de etileno que tienen una densidad de 0.908 a 0.925 g/cm3, un índice de fusión de 0.5 a 3 g/10 min, una proporción de Mw/Mn de 2 a 4, una proporción de Mz/Mw de 1.6 a 2.3, un parámetro CY-a de 0.45 a 0.6 y un perfil de ATREF caracterizado por un solo pico a una temperatura máxima de ATREF de 76 a 88 °C, y menos de 4.5 % en peso del polímero que eluye por encima de una temperatura de 91 °C. Estos polímeros de etileno se pueden utilizar para producir diversos artículos de fabricación, tales como películas sopladas y moldeadas con una combinación beneficiosa de alta resistencia al desgarro y baja opacidad.
