Abstract
Emulsions prepared using a silicone polyether as the surfactant are stable in an aqueous media in the presence of salts such as electrolytes, alcohols, solvents, and combinations thereof. The emulsions can be prepared by (i) polymerizing an unsaturated monomeric organic compound in water containing the monomer, a silicone polyether, a catalyst, and optional organic surfactants, until a polymer of desired molecular weight is obtained; (ii) by mechanically emulsifying a non-silicon atom containing organic oil in water using a silicone polyether with or without addition of other organic surfactants; and (iii) by mixing and adding a silicone polyether to a previously prepared emulsion.
