A method for producing a catalyst system consisting of a rare earth compound, an aluminium organic compound, another Lewis acid, optionally a conjugated diene and an inert inorganic or organic support material. According to said method, a solution of the rare earth compound in an inert solvent and an optionally conjugated diene and a solution of the aluminium organic compound and the other Lewis acid in an inert solvent are applied in a dosed manner to a dry, preferably agitated support material, preferably in an inert gas atmosphere, whereby the applied solution is absorbed by the support material.

L'invention concerne un procédé pour la fabrication d'un système de catalyseur constitué d'un composé des terres rares, d'un composé organique d'aluminium, d'un autre acide de Lewis, éventuellement d'un diène conjugué et d'un support inerte inorganique ou organique. Dans ce procédé, on applique de manière dosée de préférence en atmosphère inerte, sur le support séché, de préférence en mouvement, une solution du composé des terres rares dans un solvant inerte et éventuellement un diène conjugué, ainsi qu'une solution du composé organique d'aluminium et de l'autre acide de Lewis dans un solvant inerte, de telle manière que la solution appliquée soit absorbée par le support.
