to place a catalyst or other constituents on its surface this support may be used to support a transition metal catalytic precursor or can be used in another embodiment of the present invention to prepare the supported activator the activator c m n q 1 q n 1 and or m n q n as defined above is dissolved in the desired solvent described above preferably toluene c 5 c 10 hydrocarbons and combined with the halogenated support to form a slurry the reagents are mixed thoroughly using well known mixing and agitation techniques and can be mixed at any appropriate temperature depending on the reagents selected preferably room temperature this step can be performed after the halogenated support is prepared or can be accomplished simultaneously with the preparation of the halogenated support by combining all the ingredients in one step these materials can be combined at any temperature suitable for the reagents typically from about 78 u00b0 c to the reflux temperature of the halogenated reagent preferably from about 0 u00b0 c to the ref lux temperature of the solvent this can be accomplished using multiple mixing steps for example the mixing can take place for one period of time.
