Abstract: The present invention describes a metallocene catalyst based on a transition metal of group 4 or 5 of the periodic table, supported on a hybrid catalytic support provided with aliphatic organic groups, and a process for supporting metallocene on the hybrid catalytic support. The supported metallocene catalyst provides an ethylene polymer with broad or bimodal molecular weight distribution, in the presence of only one metallocene complex on the support.

Abstract: A polymer composition may include a plurality of ethylene-based polymers forming a multimodal composition distribution, each having a distinct crystallization peak in a CEF curve. A process of making a polymer composition may include melt blending a plurality of polyethylenes with different microstructural characteristics in the molten state. Another process of making a polymer composition may include polymerizing ethylene and an optional alpha olefin in combination with a plurality of metallocene catalysts in a polymerization reactor to form a plurality of ethylene based polymers. Yet another process of making a polymer composition may include polymerizing ethylene and an optional alpha olefin in combination with a multimetal catalyst in a polymerization process to form a plurality of ethylene based polymers.

Abstract: The present invention pertains to a metallocene catalyst based on a transition metal of groups 4 or 5 of the periodic table prepared by the immobilization of a metallocene complex on a support modified with hybrid soluble silica, prepared by a non-hydrolytic sol-gel process. There is also described a process for preparing said catalyst.The supported metallocene catalyst of the present invention has the advantages of high catalytic activity, morphology, besides the fact of producing copolymers of ethylene with alpha-olefins having molecular behavior that will bring benefits in mechanical properties, such as resistance to tearing, piercing and impact, as well as improved optical and weldability properties.
