Abstract

L'invention concerne de nouveaux complexes catalytiques à base de TiCl3 , ainsi qu'un procédé de préparation de ceux-ci. Ces complexes catalytiques sont obtenus par réduction de TiCl4 en présence d'une base de Lewis qui, de préférence, forme un complexe avec l'agent réducteur. L'invention s'applique à la préparation de polyoléfines perfectionnées qui sont obtenues, en utilisant ces complexes catalytiques, avec des rendements élevés et avec une stéréospécificité élevée.
