摘要： This invention is related to a method for the preparation of heterogeneous catalysts, useful for the production of poliolefins. The method is characterized because said catalysts are obtained by supporting onto solids soluble metallocenes possessing one or more functional groups. Said functional groups are characterized because they can react with other reactive groups on the surface of the solids. The reactive groups on the solids can be part of said solids or incorporated by means of chemical modification. These catalyst systems are especially appropiated for the polymerization of one or several 1-olefins having from 2 to 20 carbon atoms in their chain. Further, they are especially appropiated for the copolymerization of ethylene with 1-olefins having from 3 to 20 carbon atoms in their chains. These polymerization processes can be carried out in gas-phase slurry or solution, at high temperatures and pressures.
