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; PA1 b is 0 or an integer greater than 0; PA1 n=1 or an integer greater than 1; PA1 R.sub.f and R.sub.f ' are independently selected from the group consisting of F, Cl, perfluoroalkyl or fluorochloroalkyl; PA1 X=F, Cl, Br or mixtures thereof when n>1 PA1 X'=Cl or Br; PA1 Y is an acid group or an acid derivative easily convertible to an acid group; PA1 Z=F, Cl, Br, OH, NRR' or OA; PA1 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 PA1 A=alkali metal, quaternary nitrogen, or R. These vinyl ethers may be homopolymerized with themselves or copolymerized with other vinyl ethers.
