Catalysts for the polymerization of olefins comprise the product of the reaction between: (A) a titanium, zirconium or hafnium product with substituted cyclopentadiene ligands, (B) a mixture of two organometallic aluminium compounds, with at least one of the groups bound to the aluminium being other than a linear alkyl, and (C) water. When used in the polymerization of olefins, these catalysts show higher activities, at short residence times, than corresponding catalysts obtained from the individual components of the above-mentioned mixtures of aluminium compounds.

Les catalyseurs de polymérisation d'oléfines décrits comprennent les produits de la réaction entre (A) un dérivé de titane, de zirconium ou d'hafnium à ligands cyclopentadiène substitués; (B) un mélange de deux composés organométalliques d'aluminium dont au moins un des groupes liés à l'aluminium n'est pas un alkyle linéaire; et (C) de l'eau. Lorsqu'ils sont utilisés pour polymériser des oléfines, ces catalyseurs présentent une plus grande activité et un temps de séjour plus court que les catalyseurs correspondants produits avec les éléments individuels des mélanges susmentionnés de composés d'aluminium.
