Abstract

Los procesos de polimerización para producir plastómeros y elastómeros a base de etileno con densidades inferiores a 0.91 g/cm3 utilizan un sistema de catalizador basado en metaloceno que contiene un óxido sólido tratado químicamente. Estos procesos de polimerización se pueden realizar en un reactor de suspensión, un reactor de solución, y/o un reactor de fase gaseosa. Los polímeros de etileno producidos a partir del proceso de polimerización se pueden caracterizar por una densidad inferior a 0.91 g/cm3, un parámetro CY-a de menos de 0.2 y una relación de HLMI/MI de al menos 30, o una densidad inferior a 0.91 g/cm3, un parámetro CY-a de 0.25 a 0.75, y una relación de Mw/Mn de 2 a 3.
