Polyethylene glycol p-perfluorous nonenyloxyphenyl sulflonates(PFNPS-PEG-n) were synthesized from p-perfluorous nonenyloxyphenylsulfonyl chloride(PFNPSC) and polyethylene glycol(PEG-n),and were characterized by IR and 19F NMR,respectively.The effects of average relative molecular mass of PEG-n and reaction time on alcoholysis were investigated.The performances of these surfactants such as surface tensions,foaming characterisitics and emulsifiabilities were studied.The surface activity of PFNPS-PEG-n synthesized from PEG-600 is the best,and the optimal reaction conditions are n(PFNPSC): n((PEG-600)=1: 1,reacts at 40℃ for 6~8 h in CCl4 in the present of NEt3.The critical micelle concentration(CMC) of PFNPS-PEG-600 is 0.56 g/L,and its γCMC is 19.1 mN/m;20 mL 1 g/L PFNPS-PEG-600 will produce 95 mL foam,and its half-life time is 75 s.Emulsifiability of PFNPS-PEG-1000 is the best among PFNPS-PEG-n.
