Abstract:
A supported catalyst compossition which comprises a transitional metal catalyst precursor and a supported composition, said supported composition being prepared by a process comprisinga) reacting a Carrier having a reactive functional group LH with a halogenated organic compound RX(n)Xâ€² in the presence of a base to form a halogenated support represented by the formula Carrierâ€”Lâ€”RX(n) b) contacting the halogenated support with a Compound A to form a halogenated support composition; and c) optionally, recovering the halogenated support composition; wherein the Carrier, which has a surface, is porous, covalently bonded through L to R and comprises at least one member selected from the group consisting of talc, clay, SiO2, Al2O3, MgO, MgCl2, ZrO2, TiO2, Fe2O3, B2O3, CaO, ZnO, BaO, ThO2, aluminum phosphate gel, polyvinylchloride, hydroxy substituted polystyrene, and an organo magnesium compound represented by the formula MgR2aX2b, wherein R2 is an alkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms or an aryl group having 6 to 20 carbon atoms, X2 is a halogen, a is a number from 0 to 2 and b is a number from 0 to 2 wherein the sum of a+b=2; L is selected from the group consisting of oxygen, a boron-containing group a carbon-containing group, sulfur, a nitrogen-contasining group, and mixtures thereof and is obtained by the reaction of a reactive functional group on the Carrier with a base reactant selected from the group consisting of a metal hydroxide, an organo amine, and a metal alkyl wherein the metal is selected from the group consisting of metals from Groups 1, 2, 13 and 14 of the Periodic Table, and mixtures thereof; R is selected from the group consisting of alkyl, aryl and alkenyl; X(n) and Xâ€² are each a halogen; n is a number from 1 to 9; Compound A comprises at least one compound selected from the group consisting of [Ct]+[Mn(Q)y]âˆ’â€ƒâ€ƒI and Mn(Qn),â€ƒâ€ƒII â€ƒwherein [Ct]+ is a cation capable of activating the transition metal catalyst precursor by formation of a cation therefrom through the mechanisms of either protonation or abstraction; M is boron, phosphorus, antimony, aluminum or mixtures thereof; n is a number representing the valence state of M; and the groups Q are the same or different and are independently selected from the group consisting of halogen, halogenated organic, hydride radical, bridged and unbridged dialkylamido radicals, alkoxide and aryloxide radicals, substituted hydrocarbyl radicals, halocarbyl and substituted-halocarbyl radicals, hydrocarbyl and halocarbyl-substituted organometalloid radicals, and mixtures thereof, the number of Q groups bound to M being depicted by y which varies from 1 to n+1.
