DINUCLEAR FLUOROARYL ALUMINUM ALKYL COMPLEXES

摘要

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 compound corresponding to the formula: A f a Al2Q1 6-z, where; Q1 independently each occurrence is selected form C1-20 alkyl; Ar f i s a fluorinated aromatic hydrocarbyl moiety of from 6 to 30 carbon atoms; z is a number greater than 0 and less than 6, and the moiety: Ar f z Al2Q1 6-z is an adduct of tri(fluoroarylaluminum) with from a sub-stoichiometric to a super-stoichiometric amount of a trialkylaluminum having from 1 to 20 carbons in each alkyl group.
