Fluorinated polymers showing excellent physical and chemical properties have received much atten tion because of their wide applications. The recent progress in the studies of fluorinated polymer soap-free emulsion is reviewed. Especially their synthesis methods are described in detail, including copolymerization with polymerizable emulsifier, addition of eosolvent method, copolymerization with water-soluble monomer, addition of inorganic pow- der, addition of amphiphilic polymer and amphiphilic RAFT agent. Moreover, applications of fluorinated polymer soap-free emulsion are summarized in the functional mierospheres, surface sizing agent, leather finishing agent, textile finishing agent and coating adhesive agent. At last, the future development tendency of fluorinated polymer soap-free emulsion is proposed.
