Abstract
Abstract ompounds represented by the general formulas are prepared by reacting halofluoropropylene oxides with fluorinated acid fluorides and ketones. These compounds may be decarboxylated to form useful monomers. wherein a = 0 or an integer greater than 0; b = 0 or an integer greater than 0; c=O or 1; provided a + b + c = 0; n = zero or an integer greater than zero; R f = F, perfluoroalkyl or fluorochloroalkyl; X = F, Cl, Br or mixtures thereof when n > 1; X' = Cl or Br; Y=Cl,Br,F or 1; Z = F, 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 atom and an aryl; A = alkali metal, quaternary ammonium, R or an aryl. These monomers may then be polymerized into polymers having useful properties.
