vinylfluorid

Vinylfluorid is a nonstandard or ambiguous term that appears in some chemical literature and product catalogs. It is used inconsistently and may refer to one of two related fluorinated vinyl monomers: vinyl fluoride, with the formula CH2=CHF, and vinylidene fluoride, with the formula CH2=C(F)2. Some sources treat “vinylfluorid” as a misspelling or historical variant of either of these names, while others use it as a general label for fluorinated vinyl compounds.

In terms of structure and properties, vinyl fluoride and vinylidene fluoride are small, reactive monomers derived from vinyl groups bearing fluorine substituents. Vinyl fluoride is a monomer that forms fluorinated polymers upon polymerization, while vinylidene fluoride is primarily used to produce polyvinylidene fluoride (PVDF) and related copolymers. These monomers are typically gases or volatile liquids at room temperature and are handled under controlled conditions to prevent premature polymerization and exposure.

Production and use vary by compound. Vinyl fluoride is produced as an intermediate for fluorinated polymer and specialty monomer applications, though it is less common in bulk use than other fluorinated monomers. Vinylidene fluoride is produced industrially and polymerized to PVDF, a versatile fluoropolymer valued for chemical resistance, thermal stability, and dielectric properties. PVDF and its copolymers find applications in piping, membranes, coatings, and electronic components.

Safety and handling considerations are common to fluorinated vinyl monomers. They can be reactive and may pose inhalation or contact hazards. Proper ventilation, containment, and adherence to material safety data sheets are required, with polymerization inhibitors and standard chemical hygiene practices employed during storage and use.
