The subject of this chapter is specialty fluorinated polymers, which include amorphous perfluoropolymers, fluorinated acrylates, fluorinated polyurethanes, fluorinated thermoplastic elastomers, copolymers of chlorotrifluoroethylene and vinyl ether, and perfluorinated ionomers. This chapter describes a number of specialty fluorinated polymers which possess unique properties. It is doubtless that fluorine (F) is a special element beyond all others. F substitution for hydrogen (and many other elements) in organic compounds is relatively easy, simply because of its voracious appetite for grabbing electrons. The underlying reason is F is the most electronegative among all elements, thus forming C-F, the strongest carbon bond. Amorphous fluoropolymers are prepared by the introduction of specialty monomers. Those monomers are larger than typical fluoropolymer monomers and usually contain sizable groups that disrupt crystallization of the polymer. The reaction proceeds via free radical copolymerization, which can be carried out in either aqueous or nonaqueous media. The homopolymers and copolymers of fluoroalkyl acrylates and methacrylates are most useful for practical applications.
