Abstract

Se dan a conocer y reivindican composiciones catalizadoras que contienen metaloceno que incluyen un material de relleno o carga inerte, un método para su preparacion y un método para su uso en la produccion de poliolefinas. Las composiciones catalizadoras que contienen partículas solidas de una mezcla que consiste de: a) un catalizador de metaloceno; b) un co-catalizador capaz de activar el catalizador de metaloceno; y c) un material de relleno o carga en partículas que tiene un tamaño de partícula promedio de menos de aproximadamente 10 micrometros, que no es reactivo con el catalizador de metaloceno ni con el co-catalizador. Se preparan secando por rociadura una suspension espesa de los constituyentes.
