Abstract

Procedimiento de isomerización de metalocenos, caracterizado porque comprende calentar una mezcla de isomerización formada a partir de (i) una forma meso de un metaloceno puenteado o de una mezcla de formas meso y racémica de un metaloceno puenteado, (ii) un catalizador de isomerización a base de un haluro de un metal del Grupo 1 y/o 2 y (iii) un medio de isomerización orgánico líquido, de manera que al menos una parte de la forma meso del metaloceno se isomeriza a la forma racémica.
