摘要：
A polymerization process in aqueous emulsion of:
(I) one or more fluorinated monomers containing at least one ethylene unsaturation;
(II) one or more fluorinated monomers containing sulphonyl groups -SO 2 F;
said process comprising the use of a surfactant having the formula:
R f -X - M +
wherein
X is equal to -COO, -SO 3 ;
M is selected from H, NH 4 , alkaline metal;
R f represents a (per)fluoropolyether chain, preferably having number average molecular weight comprised between about 230 and about 1,800.
