Abstract
Procedimiento para la obtención de un sistema catalítico para la polimerización de a-olefinas en suspensión en fase gas a bajas y altas temperaturas o en masa a altas presiones y altas o bajas temperaturas. El sistema catalítico está compuesto por los componentes A y B, siendo A un conjunto de un óxido inorgánico (sílice, alúmina, arcilla) poroso funcionalizado con un compuesto A.1 silanizante, además de A.2 un órgano complejo de aluminio, tipo alquilaluminoxano con 4 a 50 grupos alquilo, y de A.3 un metaloceno de circonio, titanio o hafnio preferentemente; en el que los donadores de electrones {pi (ciclopentadieno, indeno o fluoreno) pueden estar puenteados entre sí, por una cadena de átomos de carbono, silicio, germanio o estaño. El cocatalizador B es un compuesto voluminoso perfluorado de boro y/o metilaluminoxano o alquilo de aluminio. Este sistema catalítico fija fuertemente los componentes activos al soporte, evitando su migración al medio de polimerización, consiguiéndose un buen control de la morfología, de la distribución de los tamaños de partícula y del peso molecular de los polímeros obtenidos. Además, presenta una elevada actividad en la reacción de polimerización con lo que se reduce el nivel de contaminación de los polímeros.
