ABSTRACT OF THE DISCLOSURE A method of preparing a monomer of the formula Image (I) which comprises reacting a compound of the formula Image for sufficient time and at a sufficient temperature to form said compound (I) wherein a = 0 or an integer greater than 0; b = 0 or an integer greater than 0; n = 0 or an integer greater than 0; m = 0 or an integer greater than 0; Rf and Rf are independently selected from the group consisting of F, C1, perfluoroalkyl radicals and fluorochloroalkyl radicals; X = F, C1, Br, or mixtures thereof when n>1; X' is independently C1 or Br; 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 atom and an aryl; A = alkali metal, quaternary nitrogen, or R; Y = I, Br, C1, or F, the monomer thus produced being suitable for copolymerisation to yield poly- mers with desirably modified physical properties, such as lower melting point to facilitate fabrication.
