Perfluorinated Vinyl Ether

As a special fluorine containing monomer perfluorinated vinyl methyl ether is widely applied in the development of new fluoroplastics and fluorine rubber with comprehensive performance.

Perfluorinated vinyl ether.

We named this process perfect that is the abbreviation of perfluorination of an esterified compound then thermal elimination. A method is provided for making a perfluorinated vinyl ether having a sulfonyl fluoride end group according to the formula fso 2 cf 2 n o cf cf 2 where n is 2 5 comprising the steps of. In these materials the ether groups are pendant from the polymer backbone. To produce fso 2 cf 2 n 1 cof.

Their chemical formula is f cf cf 3 cf 2 o n cf 2 cf 3. Tetrafluoroethylene perfluoro alkoxy vinyl ether 44 product results match criteria. Perfluorinated vinyl methyl ether. The perfluorinated ionomers are copolymers of tetrafluoroethylene tfe and perfluorinated vinyl ether terminated by an ionic group typically a sulfonic acid or in some cases a carboxylic acid or a sulfon amide group.

The ether groups are integral to the polymer chain. Offers high heat resistance excellent chemical resistance low smoke flame characteristics excellent dielectric properties excellent. Nafion is a perfluorinated polyether with pendant sulfonic acid. Pfcs have properties that result from the presence of fluorocarbons containing only c f and c c bonds and the functional group common functional groups in pfcs are oh co 2 h chlorine o and so 3 h.

The total process to a perfluorinated vinyl ether is shown in scheme 6. Fluon pfa p 63p by agc is a general purpose perfluoroalkoxy pfa grade copolymer of tetrafluoroethylene and perfluorinated vinyl ether.

Krytox is a grease generated by the polymerization of hexafluoropropylene oxide. A perfluorinated compound pfc is an organofluorine compound containing only carbon fluorines and c c bonds but also other heteroatoms. It can copolymerize with tetrafluoroethylene to form perfluorinated ether elastomer with properties of.
