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.

Abstract: The present invention relates to a suspension polymerization process for the production of ultra high molecular weight polyethylene, wherein the operation is carried out in at least two reactors of the CSTR type (continuous stirring tank reactor), in a serial configuration, wherein the first reactor is fed with solvent, monomer and, optionally, comonomer; Ziegler-Natta type catalyst, said catalyst composition having a chloride concentration of at least 55%, based on its composition, and preferably more than 76%, chlorinated cocatalyst and chain growth regulator, said continuous stirring tank reactor being kept under a pressure between 0.1 to 2.0 MPa and temperature from 40° C. to 100° C., which contents of the first reactor are transferred to the subsequent reactor, by means of a pressure differential or through pumping, wherein said subsequent reactors are kept under a pressure between 0.1 to 2.0 MPa and temperature from 40° C. to 100° C., and fed with solvent, monomer, and, optionally, comonomer, catalyst, cocatalyst and chain growth regulator, the pressure and temperature in each of the reactors being different from one another up to the "nth" reactor, the number of reactors "n" varying from 2 to 4; the suspension thus obtained in reactor "n" being centrifugated for the removal of solvent and dried in a fluidized bed drier; thereby resulting in an ultra high molecular weight polyethylene homopolymeric or copolymeric composition with polydispersity greater than or equal to 6.
