Synthèse et polymérisation de monomères fluorés acryliques substitués en position α. Partie III. Synthèse et polymérisation de l'α-heptadécafluoro-undécanoyloxyacrylate d'éthyle
摘要:
The synthesis of ethyl alpha-heptadecafluoro-undecanoyloxyacrylate (3), H2C = C(O-CO-CH2CH2C8F17)CO2CH2CH3, has been performed in three steps starting from ethyl bromopyruvate and heptadecafluoro-undecanoic acid, with an overall yield of c. 70%. The homopolymerization and copolymerization of 3 have been easily carried out. From the kinetic study of homopolymerization and copolymerization of monomer 3 with styrene, k(p)(2)/k(Tc) and r(1), r(2), the reactivity ratios of the two monomers, can be determined.
