METALOCENAL CATALYST SUPPORTED IN HYBRID SUPPORT, PROCEDURE FOR OBTAINING IT, POLYMERIZATION PROCESS FOR OBTAINING AN EOMIC HOMOPOLYMER OR COPOLYMER WITH DISTRIBUTION OF LARGE OR METAL BALODIUM OF THE METAL PIPELINE AND METALBALL DIMENSION BIMODAL

摘要

patent-based metallocene catalyst, process for obtaining it, polymerization process for obtaining a broad or bimodal molar mass ethylene homopolymer or copolymer, use of supported metallocene catalyst and ethylene polymer with broad or bimodal molar mass distribution ". The present invention relates to a transition metal-based metallocene catalyst of groups 4 or 5 of the periodic table supported on a hybrid catalytic support having aliphatic organic groups. Also described is a metallocene support process on said hybrid catalytic support provided with aliphatic organic groups. The supported metallocene catalyst of the present invention has as its main advantage that it produces an ethylene polymer with broad or bimodal molar mass distribution using only one type of metallocene complex on the support. As a result, a better processability of the obtained resin is obtained and, therefore, a potential reduction in processing cost.
