Abstract

Se describe un componente sólido de catalizador altamente activo en la (CO)polimerización de etileno que contiene titanio, magnesio, aluminio, cloro y grupos alcoxi, y se obtiene por medio de un procedimiento en donde: (i) un sólido, apoyo granular de cloruro de magnesio, obtenido mediante secado por rocío de una solución alcohólica de cloruro de magnesio, se suspende en un solvente hidrocarbonado líquido, y se agregan un alcohol alifático y un tetraalcóxido de titanio a la suspensión obtenida de este modo, (ii) la suspensión del paso (i) se calienta hasta que se obtiene una solución homogénea, y la solución se enfría para precipitar un sólido granular, (iii) el sólido granular obtenido en el paso (ii), en la suspensión relativa, se pone en contacto y se hace reaccionar con un alquilhaluro de aluminio, y (iv) el componente sólido catalizador se recupera de los productos de reacción del paso (iii).
