The synthesis of 2-perfluorohexylethyl alpha-acetoxyacrylate(b)) H2C=C(OAc)CO2C2H4C6F13 (1) was performed in two steps starting from Pyruvic acid and 2-perfluorohexylethanol (3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluoro-1-octanol) with an overall yield of about 50%. Esterification of pyruvic acid with the adequate fluorinated alcohol was followed by enol acetylation to give monomer 1. Homopolymerization and copolymerization of 1 are easily carried out. From the kinetic study of the homopolymerization and copolymerization of 1 with styrene, the numerical values of the ratio square of the rate constant of propagation over the rate constant of termination k(p)2/k(t) and of the copolymerization reactivity ratios r1 and r2 of the two monomers were determined.
