Abstract:
A composition comprising:a polymeric material having at least one polar group and having at least one pendant group comprising an Rf group, said polymeric material having at least 2 repeat units, wherein each said at least one polar group, independently, is an anion-countercation; or a cation-counteranion; or an amphoteric group; wherein each said Rf group, independently, is a fluorinated linear alkyl having from 1 to about 7 carbon atoms, or a fluorinated branched alkyl wherein the longest chain is from 1 to about 7 carbon atoms and each branch, independently, contains from 1 to about 3 carbon atoms, and each Rf, whether linear or branched, has at least one carbon atom bonded to at least one fluorine atom, and wherein each Rf group, independently, has at least 25% of the non-carbon atoms being fluorine atoms and the remaining non-carbon atoms being H, I, Cl, or Br, and wherein said polymer is derived from: a cyclic ether monomer having at total of from 2 to 5 carbon atoms in the ring with a total of 1 to 20 substituted carbon atoms, or dioxane, or dioxalane, or trioxane.
