摘要

Abstract invention patent: "metaloceno catalyst supported on hybrid support, process for obtaining the same polymerization process to obtain a homopolymer or copolymer of ethylene with broad or bimodal molar mass distribution, the use of the catalyst of metaloceno suport ADO and polymer of ethylene with broad or bimodal molar mass distribution.The present invention relates to a catalyst metaloceno based transition metal of groups 4 and 5 of the periodic table supported on a support the catalytic hybrid with aliphatic organic groups. It is also described a process of backing up metaloceno on said catalytic support hybrid with aliphatic organic groups.The catalyst of the present invention metaloceno supported presents as the main advantage the fact that produce a polymer of ethylene with broad or bimodal molar mass distribution by using only one type of complex metaloceno on the support. As a result, obtains a better processability of the resin obtained and, therefore, a potential reduction of processing cost.
