Embodiment 1
[0060] The structure of the acrylate containing perfluoropolyether chain synthesized in this embodiment is as follows:
[0061]
[0062] where Rf- is:
[0063]
[0064] 1) Synthesis of N-hydroxyethyl perfluoropolyether sulfonamide
[0065] Add 10.4g (0.1mol) of N-hydroxyethylethylenediamine, 50ml of anhydrous ether, and 50ml of methyl acetate into a 500ml reaction bottle, slowly add 142.4g (0.2mol) of all After the addition of methyl fluoropolyether sulfonate was completed, the ice-water bath was removed, and the reaction was continued for 10 hours. Then, the low-boiling components were removed by distillation with a rotary evaporator, and the intermediate N-hydroxyethyl perfluoropolyether sulfonamide was obtained after vacuum drying.
