    Abstract: Activator solid support for metallocenes as catalysts in the polymerization of olefins, characterized in that it consists of a group of support particles for a solid catalytic component, which are formed from at least one porous mineral oxide, the said particles having been modified in order to carry, on the surface, aluminium and/or magnesium Lewis-acid sites of formula: or —Mg—F, the groups coming from a functionalization agent having reacted with —OH radicals carried by the base particles of the support, the functionalization reaction having been followed by a fluorination reaction. The catalytic system according to the invention comprises (a) a metallocene catalyst, which has, if required, been subjected to a prealkylation treatment; (b) a cocatalyst; and (c) an activator solid support for metallocene, as defined above, it being possible for the cocatalyst (b) to be absent if the metallocene catalyst (a) has been prealkylated.

    Abstract: This invention provides an article, compositions, methods of making and uses of vapor-deposited metal compounds immobilized on porous substrates. The substrate is a porous substrate having an average pore size of at least about 8 Å and a surface area of at least about 10 m2/g. The methods describe the vapor-deposition of an inorganic compound onto the substrate where the deposition is accomplished with a relatively small amount of ligand loss. The substrate can be pre-treated to achieve a uniformly dispersed metal compound deposited on the substrate. The inorganic compound can decompose into a metal compound. The article can also function as a catalyst for carbon-heteroatom coupling reactions such as carbon-carbon coupling reactions, most notably, the Heck reaction.
