The present invention relates to a catalyst system based on monoazadiene metal complexes of the formula (see fig. I), and a co-catalyst suitable for activating the metal complex, and to the use of the catalyst system for the polymerization of unsaturated compounds, especially for the polymerization and copolymerization of olefins and/or dienes. The novel catalyst system is characterised in particular by its ease of access, its lack of sensitivity to external influences and its ease of handling.
La présente invention porte sur un système catalytique à base de complexes métalliques de monoazadiène de formule (voir fig. I), et d'un cocatalyseur permettant d'activer le complexe métallique, ainsi que sur l'utilisation dudit système catalytique pour la polymérisation de composés insaturés, notamment la polymérisation et la copolymérisation d'oléfines et (ou) de diènes. Le nouveau système catalytique est caractérisé par une grande accessibilité, l'absence de sensibilité aux influences externes et la facilité de manipulation.
