<p>Novel vinyl ethers are prepared in decarboxylation reactions of novel acid fluoride compounds according to the following reaction: wherein a is O or an integer greater than O; b is O or an integer greater than O; n = 1 or an integer greater than 1; Rf and R? are independently selected from the group consisting of F, C1, perfluoroalkyl or fluorochloroalkyl; X = F, Cl, Br or mixtures thereof when n > 1 X' = C1 or Br; Y is an acid group or an acid derivative easily convertible to an acid group; Z = F, C1, Br, OH, NRR' or OA; R and R' are independently selected from the group consisting of hydrogen, an alkyl having one or more than one carbon atoms, and aryl; and A = alkali metal, quaternary nitrogen, or R. These vinyl ethers may be homopolymerized with themselves or copolymerized with other vinyl ethers. 28,979-F</p> |
