Abstract

Un procedimiento para la polimerización catalítica de etileno solo o con una o más alfa-olefinas adicionalescaracterizado porque comprende emplear como medio catalizador una composición catalítica de polimerización de etileno preparada mediante los pasos de: (1) secar un soporte de catalizador de óxido inorgánicocon una elevada área superficialseleccionado entre el grupo que comprende alúminatoriasílicezirconia y mezclas de los mismos a una temperatura de 100ºC a 800ºC ; (2) suspender el soporte seco obtenido en el paso (1) con un hidrocarburo normalemente líquido anhidro; (3) mezclar la suspensión obtenida en el paso (2) con una solución de un compuesto de cromoceno en un hidrocarburo normalmente líquido y un compuesto de titanio que sea soluble en dicho hidrocarburo y sea calcinable dando TiO2 por lo cual la mezcla resultantefuera del hidrocarburocontiene 002 a 30% ponderal de cromo elemental y 10 a 10% ponderal de titanio elemental; (4) eliminar el hidrocarburo dejando un residuo sólido; (5) agregar al residuo del paso (4) de 0 a 25% ponderal de un agente de fluoración calculado como F; y (6) calentar el producto del paso (5) en una atmósfera con contenido de oxígeno sustancialmente anhidra a una temperatura de 300ºC a 1000ºC hasta que se obtiene un catalizador activo de polimerización de etileno.
