Activating supports are prepared by (a) combining (i) fluorine-containing compounds having a reactive group and (ii) an organometallic compound, (b) contacting a porous mineral oxide support material with the mixture from step (a), (c) heating the functionalized support from step (b) under an inert gas and then under an atmosphere comprising oxygen, and (d) recovering the activating support. The fluorine-containing compounds may have the formula R(Fn)-X wherein R is hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl with up to 20 non-hydrogen atoms, n is 1-41, X is OH, SH or NR′2, R′ is hydrogen or hydrocarbyl. The activating supports are useful in combination with transition metal catalysts for polymerization of olefins, e.g., with metallocene complexes. Preparation of the activating supports is easier and more economic than prior methods and provides for supported polymerization catalyst systems having excellent activities. Polymers produced using the activating supports exhibit improved rheology properties.
An activating support having a F/Al molar ratio in the range 1.8-10 prepared by the steps of
An activating support having a F/Al molar ratio in the range 1.8-10 comprising a porous mineral oxide support material, fluorine and a Group 1, 2 or 13 metal, said support prepared by a method comprising contacting a fluorine-containing compound having a reactive group, an organometallic compound having a Group 1, 2 or 13 metal and said porous mineral oxide support material, wherein the organometallic compound and fluorine containing compound are contacted together before contact with the porous mineral oxide support material.
An activating support having a F/Al molar ratio in the range 1.8-10 comprising a porous mineral oxide support material, fluorine and a Group 1, 2 or 13 metal, said support prepared by a method comprising contacting a fluorine-containing compound having a reactive group, an organometallic compound having a Group 1, 2 or 13 metal and said porous mineral oxide support material, wherein the organometallic compound is contacted with the porous mineral oxide support material before the addition of the fluorine containing compound.
