Abstract
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 neutral (Lewis acid) or charge separated (cation/anion pair) comprising a boron ligand containing a fluorinated organic group containing from 10 to 1000 non-hydrogen atoms.
