Abstract
Sistemas de catalizadores heterogéneos tipo metaloceno, para procesos de obtención de poliolefinas. Esta invención se refiere a un método de obtención de catalizadores heterogéneos o insolubles en el medio de reacción para la obtención de poliolefinas. El procedimiento está caracterizado por la preparación de los sistemas catalíticos mediante soporte de catalizadores solubles del tipo metaloceno, conteniendo uno o más grupos funcionales capaces de reaccionar con los grupos reactivos, ya existentes o incorporados por modificación química previa, de soportes inorgánicos. Estos sistemas de catalizadores son especialmente apropiados para la polimerización de uno o varios 1-alquenos con 2 a 20 átomos de carbono, así como para la copolimerización de etileno con 1- alquenos con 3 a 20 átomos de carbono, en plantas de producción de poliolefinas que emplean los catalizadores en suspensión en un disolvente o en fase gaseosa, así como para la polimerización en masa a altas temperaturas y presiones.Heterogeneous metallocene catalyst systems, for processes to obtain polyolefins. This invention relates to a method of obtaining heterogeneous or insoluble catalysts in the reaction medium for obtaining polyolefins. The process is characterized by the preparation of the catalytic systems by means of support of soluble catalysts of the metallocene type, containing one or more functional groups capable of reacting with the reactive groups, already existing or incorporated by prior chemical modification, of inorganic supports. These catalyst systems are especially suitable for the polymerization of one or more 1-alkenes with 2 to 20 carbon atoms, as well as for the copolymerization of ethylene with 1- alkenes with 3 to 20 carbon atoms, in polyolefins production plants which employ the catalysts in suspension in a solvent or in the gas phase, as well as for mass polymerization at high temperatures and pressures.
