<p>A catalyst activator particularly adapted for use in the activation of metal complexes of metals of Group 3-10 for polymerization of ethylenically unsaturated polymerizable monomers, especially olefins, comprising: a composition comprising a mixture of aluminum containing Lewis acids said mixture corresponding to the formula: [(-AlQ1-O-)z (-AlArf-O-)z'](Arfz''Al2Q16-z'') where Q1 independently each occurrence is selected from C¿1-20? alkyl; Ar?f¿ is a fluorinated aromatic hydrocarbyl moiety of from 6 to 30 carbon atoms; z is a number from 1 to 50, preferably from 1.5 to 40, more preferably from 2 to 30, and the moiety (-AlQ1-O-) is a cyclic or linear oligomer with a repeat unit of 2-30; z' is a number from 1 to 50, preferably from 1.5 to 40, more preferably from 2 to 30, and the moiety (-AlArf-O-) is a cyclic or linear oligomer with a repeat unit of 2-30; and z'' is a number from 0 to 6, and the moiety (Arfz''Al2Q16-z'') is either tri(fluoroarylaluminum), trialkylaluminum, or an adduct of tri(fluoroarylaluminum) with a sub-stoichiometric to super-stoichiometric amount of a trialkylaluminum.</p> |
