The synthesis of ethyl, α-perfluorooctylmethylacrylate (1), has been performed in three steps starting from perfluorooctylpropionic acid, with an overal yield of 82percent.Esterification of the acid by ethanol was followed by ethoxalylation in the α position (92percent yield).The last step involved the addition of formaldehyde on to the keto ester to produce an α-keto-γ-lactone which could be hydrolyzed in an aqueous basic medium to give the monomer 1 in 90percent yield.The homopolymerization of 1 is difficult but copolymerization with styrene and N-vinylp yrrolidone can be readily carried out.Elemental analysis and 1H NMR spectral data provide information on the copolymer composition.
