    Abstract: Rotational moulding process for polymerizing or copolmerizing ethylene for manufacturing ethylene polymers or copolymers having a controlled particle size and morphology. Ethylene is polymerized or copolymerized under ethylene polymerizing conditions in the presence of a supported metallocene catalyst, where the average particle size of the catalyst particles is selected within the range of 14-40 nullm and the residence time at the polymerization is selected so as to achieve a polymer where average particle size is between 0.2-0.5 mm and the proportion of fractions between 0.1-0.6 is at least 80%.

    Abstract: An organometallic composition which can be used as activating component in a metallocene catalyst for the (co)polymerization of null-olefins, comprises: (A) a fluorinated di-unsaturated cyclic compound, having a relatively acid hydrogen atom, (B) an organometallic compound sufficiently basic to react with the acid hydrogen of the above compound (A), and (C) a polar aprotic organic compound, not containing metallic atoms, having a dielectric constant, in the pure state, equal to or greater than 2, and a weak coordinating capacity. Said composition allows a metallocene catalytic system of the ionic type to be obtained, with a high activity in the (co)polymerization of olefins and a reduced content of metallic residue in the polymeric product thus obtained.

    Abstract: Processes of producing fluorided catalyst compounds and process of producing polyolefins using these catalyst compounds are disclosed. An embodiment of the process includes contacting a nitrogenous metallocene compound with a fluoriding agent, which preferably includes a fluorided anhydrous acid, for a time sufficient to form a fluorided metallocene catalyst compound. An example of the process to produce a fluorided metallocene is: 1 wherein N is nitrogen, R and Rnull are groups selected from hydrogen, hydrocarbons, heteroatom-containing hydrocarbons and halides, p can be 0 (if no substituent groups are present on the Cp rings) or an integer from 1 to 5; adjacent R groups can form another ring system (e.g., to form a tetrahydroindenyl or indenyl group); and the other groups are defined as herein; wherein nullEq.null are the equivalents of fluoriding agent combined with the nitrogenous metallocene compound ranging from 1 to 10 in one embodiment.
