Abstract
1.Procedimiento para la polimerización de una o más olefinas que tienen de 2 a 8 átomos de carbono en presencia de un catalizador producido por incorporación de un compuesto de cromo en un soporte que contiene sílice, caracterizado porque se emplea un catalizador que ha sido obtenido poniendo en contacto a elevada temperatura dicho soporte que contiene sílice antes de la incorporación del citado compuesto de cromo con un ambiente tratante elegido entre: (1) monóxido de carbono (2) un componente que contiene bromo o (3) un componente que contiene oxígeno y azufre.
