Abstract
De acuerdo con una o más modalidades, una composición de polietileno, que puede incluir una primera área de fracción de polietileno definida por un área en un perfil de elución mediante el método de análisis de iCCD en un intervalo de temperatura de 45 °C a 90 °C; un primer pico en el intervalo de temperatura de 45 °C a 90 °C en el perfil de elución; una segunda área de fracción de polietileno definida por un área en el perfil de elución en un intervalo de temperatura de 90 °C a 120 °C; un segundo pico en el intervalo de temperatura de 90 °C a 120 °C en el perfil de elución; y un mínimo local en un intervalo de temperatura de 80 °C a 95 °C en el perfil de elución. La composición de polietileno puede tener una densidad de 0.924 g/cm3 a 0.936 g/cm3 y un índice de fusión (I2) de 0.5 g/10 minutos a 1.2 g/10 minutos. Una relación de la primera área de fracción de polietileno a la segunda área de fracción de polietileno puede ser 2.0 a 4.0.
