Zusammenfassung:	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 agr; olefins. Se provee catalizadores soportados de heterometaloceno, donde el soporte es un material polimerico en particulas. Los catalizadores tienen un complejo de metal de transicion que contiene por lo menos un ligando heteroatomico anionico, estable a la polimerizacion, asociado con el metal de transicion, y un compuesto activador de boro, depositado sobre el soporte. Los soportes polimericos usados para los catalizadores de heterometaloceno de la invencion son homopolimeros de etileno y copolimeros de etifeno y alfa-olefinas de 3 a 8 atomos de carbono.
