Production of Perfluorodioxole and Amorphous Fluoropolymer
Published: December 2003
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.
