Abstract
Abstract Novel vinyl ethers are prepared in decarboxylation reactions of novel acid fluoride compounds according to the following reaction: ##STR1## wherein a is 0 or an integer greater than 0; b is 0 or an integer greater than 0; n=1 or an integer greater than 1; R f and R f ' are independently selected from the group consisting of F, Cl, perfluoroalkyl or fluorochloroalkyl; X=F, Cl, Br or mixtures thereof when n>1 X'=Cl or Br; D is an acid group or an acid derivative easily convertible to an acid group; Z=F, Cl, 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.
