Perfluorodioxole is an important class of fluoromonomer used to produce
a relatively new type of fluoropolymers known as amorphous fluoropolymer.
Amorphous fluoropolymer is a copolymer produced by the polymerization of tetrafluoroethylene
and a perfluorodioxole. The copolymer exhibits the excellent chemical, thermal,
and surface properties associated with perfluorinated polymers. The copolymer
also possesses unique electrical, optical and solubility characteristics.
In this review, we evaluated the production of a perfluorodioxole fluoromonomer,
2,2-bistrifluoromethyl-4,5-difluoro-1,3-dioxole (PDD), and the production
of amorphous fluoropolymer. The design is based on a plant capacity of 100
metric tons of amorphous fluoropolymer per year. Current consumption of amorphous
fluoropolymer is negligible.
