Somewhat between PTFE and PFA materials is the product Hostaflon TFM, which is a copolymer of TFE and a small amount of the perfluoro(propyl vinyl ether). It has improved impact strength and weldability and has been promoted as a suitable material for forming into bottles. Yet another TFE-perfluoroalkoxy copolymer was introduced by Du Pont in 1979 as Teflon EPE. This material had a somewhat lower melting point (295 °C) than the more common PFA fluoropolymers but it is no longer marketed. [Pg.378]

Perfluoroalkoxy (PFA) is very like PTFE with very similar fluorine content and properties, but it is melt processable and more expensive. [Pg.475]

The nitro groups in TNB were replaced with alkoxy [7, 8] or perfluoroalkoxy [9-15] groupings using aromatic nucleophilic nitrodisplacement reaction [16-19] in accordance with Scheme 4.4. Monosubstituted dinitro compounds thus obtained were reduced to the corresponding diamines [7, 8, 11-15] in accordance with Scheme 4.5. The simplest of the target diamines, 3,5-diaminoanisole [7, 20, 21], was prepared in accordance with Scheme 4.6. [Pg.31]

Screening tests were conducted on potential construction materials. The candidate materials evaluated included the following polytetrafluoroethylene (PTFE, TFE), fluorinated ethylene-propylene copolymer (FEP), perfluoroalkoxy-alkanes (PFA), ethylene-tetrafluoroethylene copolymer (ETFE), ethylene-chlorotrifluoroethylene copolymer (E-CTFE), poly vinylidene fluoride (PVDF), polypropylene (PP), and polyvinyl chloride (PVC). These materials were chosen based on cost, availability, and information from manufacturers on compatibility with acid solutions. [Pg.317]

Regardless of which mechanism occurs, it is necessary that either C2FsO or C2F5CFXO or both spontaneously decompose by C—C bond cleavage at room temperature. This is in marked contrast to the corresponding hydrocarbon alkoxy radicals. Further evidence for the instability of perfluoroalkoxy radicals has been discussed by Barr, Francis, and Haszeldine.19...
