CA 2310647

The present invention relates to a catalyst component comprising a compound of a metal selected from the group consisting of Co, Ni and rare earth elements supported on a polymer having a porosity (mercury) higher than 0.02 cm3/g. The use of the above catalyst component makes it possible to prepare dienic polymers, in gas-phase with high yields.

L'invention concerne un composant de catalyseur comprenant un composé métallique choisi dans le groupe constitué par Co, Ni et des éléments de terre rare, et supporté sur un polymère dont la porosité (essai au mercure) est supérieure à 0,02 cm?3¿/g. L'utilisation de ce composant de catalyseur permet de préparer des polymères diéniques, en phase gazeuse, et d'obtenir des rendements importants.
