The subject invention more specifically reveals an emulsion polymerization process that comprises: (1) preparing a monomer solution which is comprised of (a) at least one monomer, (b) a conjugate acid of a surfactant with a [pK.sub.a] of less than 14, and (c) a controlled free radical polymerization agent; (2) preparing an aqueous medium which is comprised of (a) water, and (b) a conjugate base of a weak acid wherein the [pK.sub.b] of the base is less than 14; (3) mixing the monomer solution with the aqueous medium under conditions that result in the in-situ formation of an emulsifier; and (4) initiating free radical polymerization.

Controlled polymerization

With a pKa of 12.1, for its conjugate acid in aqueous solution, 1,8-bis(dimethylamino) naphthalene is one of the strongest amine bases known, although it only absorbs protons slowly-hence the trade name.
