Supported heterometallocene catalysts wherein the support is a particulate polymeric material are provided. The catalysts have a transition metal complex containing at least one anionic, polymerization stable heteroatomic ligand associated with the transition metal and a boron activator compound deposited on the support. Polymeric supports used for the heterometallocene catalysts of the invention are homopolymers of ethylene and copolymers of ethylene and C3-8 .alpha.-olefins.
La présente invention concerne des catalyseurs hétérométallocènes supportés dans lesquels le support est une matière polymère particulaire. Les catalyseurs présentent un complexe de métal de transition contenant au moins un ligand hétéroatomique anionique, stable en polymérisation, associé au métal de transition, et un composé d'activation de bore déposé sur le support. Les supports polymères utilisés pour les catalyseurs hétérométallocènes de l'invention sont des homopolymères d'éthylène, des copolymères d'éthylène et des .alpha.-oléfines C¿3-8?.
