  Fluoropolymer - Wikipedia, the free encyclopedia
A fluoropolymer is a polymer that contains atoms of fluorine.
Fluoropolymers were discovered serendipitously in 1938 by Dr. Roy J. Plunkett.
He was working on freon (for the DuPont corporation) and accidentally polymerized tetrafluoroethylene.

 Conductive melt-processible fluoropolymer - Patent 6582628
The aqueous dispersion of melt-fabricable fluoropolymer is coagulated to form a coagulum of the fluoropolymer, typically by the addition of electrolyte to the aqueous medium and agitating the dispersion.
Fluoropolymer coagulum particles and powder composition are prepared as in Example 1 but with solvent granulation using 10 kg of 1,1,1,2,3,4,4,5,5,5-decafluoropentane after addition of 500 g of 60% nitric acid to form large granules of the coagulated fluoropolymer.
Fluoropolymer coagulum particles made according to the teaching of this invention and acetylene fl are combined as described in Example 1 except that a Henshel mixer is used.

While the fluoropolymer will generally be used in forming some or all of the cover of the golf ball, it may also or alternatively comprise some or all of the core, and/or an intermediate layer(s).
A fluoropolymer is generally an olefinic polymer in which monomers containing units of the formula --(H)C.dbd.C(H)--, wherein one or more of the hydrogen atoms in the monomer is replaced by fluorine atoms, are reacted with identical monomers or, more usually, one or more different monomers to form a polymer.
