Abstract
Abstract A novel class of monomeric emulsion stabilizers consists of certain types of ethylenically-unsaturated radicals covalently linked to a quaternary nitrogen atom which in turn is covalently linked to a lipophilic radical. Such monomers will polymerize with other ethylenically-unsaturated radicals forming self-stabilized, surfactant-free polymeric dispersions.
