Abstract
En varias modalidades, la formulación de polietileno tiene una densidad mayor de 0,940 g/cm3 cuando se mide de acuerdo con ASTM D792, y un índice de fusión de alta carga (I21) de 1,0 g/10 min a 10,0 g/10 min cuando se mide de acuerdo con ASTM D1238 en 190 °C y una carga de 21,6 kg. Además, la formulación de polietileno tiene un peso molecular pico (Mp(GPC)) de menos de 50.000 g/mol, un peso molecular promedio en número (Mn(GPC)) de menos de 30.000 g/mol, y una fracción en peso (w1) de peso molecular (MW) menor de 10.000 g/mol menor o igual a 10,5 % en peso, según lo determinado por cromatografía de permeación en gel (GPC). También se proporcionan artículos fabricados a partir de la formulación de polietileno, tales como artículos fabricados mediante procesos de moldeo por soplado.
