Claim Text:
1. Supported bimetallic catalysts, wherein said catalysts are formed by the mixture of two transition metals in a catalytic support and an activator based on one or more organometallic compounds selected from the group consisting of trimethylaluminum (TMAL), triethylaluminum (TEAL), tri-isobutilaluminum (TIBAL), tri-n-hexylaluminum (TNHAL), tri-n-octilaluminum (TNOAL), dimethylaluminum chloride (DMAC), methylaluminum dichloride (MADC), diethylaluminum chloride (DEAC), ethylaluminum dichloride (EADC), di-isobutylaluminum chloride (DIBAC), isobutylaluminum dichloride (MONIBAC), ethylmagnesium butyl (BEM), octilmagnesium butyl (BOMAG) and di-n-hexylmagnesium (DNHM), in the presence of an organic solvent of the aliphatic hydrocarbon group, wherein said catalysts are formed by the mixture of two or more metallocenes having transition metals of group 5 of the Periodic Table, and ligands selected from the group consisting of alkyl, monoindenyl and monofluorenyl groups, substituted or not, and wherein said catalytic support is formed by a silica containing a mixture of one or more organometallic compounds of groups 2 or 13 of the Periodic Table, at least one magnesium-based compound and a polar solvent.
