The title monomer (4) was prepared from the trimer of hexafluoropropene-1, 2-oxide, 2, 4, 4, 5, 7, 7, 8, 8, 9, 9, 9-undecafluoro-2, 5-bis (trifluoromethyl)-3, 6-dioxanonanoyl fluoride (1), via methyl ester 2 that was reduced by sodium borohydride to the corresponding alkanol 3, which was finally acylated by methacryloyl chloride.
