The present invention relates to a process for the polymerization of fluoromonomers in an aqueous medium, said process comprising the steps of: forming an aqueous emulsion comprising a 2-Alkoxy acetate surfactant and fluoromonomer in a reactor; and initiating polymerization of said fluoromonomer by adding an initiator into the reaction mixture. Preferably, the surfactant used in the instant process is either Sodium 2-[(2-hexyldecyl)oxy] acetate or Sodium-2-dodecyloxyacetate.
