ABSTRACT:
An ionic catalyst system component comprising a water-stable anion having a plurality of lipophilic radicals covalently coordinated to and shielding a central, formal charge bearing metal or metalloid atom, in which the lipophilic radicals of the anion include substituted aromatic radicals useful for polymerizing olefins, diolefins, or acetylenically unsaturated monomers, either alone or in combination with each other or with other polymerizable monomers is disclosed. A method of using the anion to stabilize ionic catalyst systems during polymerization is also disclosed.
