    摘要: Isobutylene homopolymers and copolymers are prepared using a catalyst system comprising a haloadamantane component and a Lewis acid. Branched polymers are prepared using polyhaloadamantanes, the branches being attached to the adamantane at the former location of the halide. The preferred catalyst systems are diethylaluminum chloride and bromoadamantane as well as polybromo, or polychloroadamantanes.

    摘要: 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: wherein N is nitrogen, R and Rα 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 “Eq.” are the equivalents of fluoriding agent combined with the nitrogenous metallocene compound ranging from 1 to 10 in one embodiment.
