When mixed with Lewis acids, new donor ligand-substituted 5-organyl-chromium complexes form highly active polymerisation catalysts for .alpha.-alkenes, their mixtures and mixtures of .alpha.-alkenes and unsaturated alkenes with a stretched double bond.
Ces nouveaux complexes ??5¿-organyle-chrome substitués par des ligands donneurs constituent, lorsqu'ils sont mélangés à des acides de Lewis tels que l'aluminoxane, de méthyle des catalyseurs extrêmement actifs de la polymérisation d'alcènes-.alpha. et de leurs mélanges, ainsi que de mélanges d'alcènes-.alpha. et d'alcènes insaturés à liaison double étirée.
