Ae. Feiring, SYNTHESIS OF NEW FLUOROPOLYMERS - TAILORING MACROMOLECULAR PROPERTIESWITH FLUORINATED SUBSTITUENTS, Journal of macromolecular science. Pure and applied chemistry, A31(11), 1994, pp. 1657-1673
The challenges and opportunities in the preparation of new fluoropolym
ers are illustrated by the synthesis of fluorinated poly(ether sulfone
s), polyimides, and polyethers. Synthetic methods used for the prepara
tion of new fluorinated monomers and polymers include anion-radical su
bstitutions of perfluoroalkyl diiodides, nucleophilic additions to flu
orinated olefins, perfluoroalkylsulfonyl-mediated nucleophilic substit
utions, and direct fluorinations with elemental fluorine. Properly pla
ced fluorinated substituents can have significant effects on the diele
ctric properties, thermal stability, moisture absorption, permeability
, phase transitions, and reactivity of the resulting polymers. In addi
tion, fluorinated groups can enhance nonlinear optical effects and pro
vide a method for chromophore alignment. The special behavior of parti
ally fluorinated substituent groups offers unique tools for tailoring
macromolecular properties.
