Vinyl and Vinylidene Polymers
Vinyl groups can polymerize with the aid of a radical initiator or a catalyst, forming vinyl polymers. In these polymers, the double bonds of the vinyl monomers turn into single bonds and the different monomers are joined by single bonds. Vinyl groups do not exist in vinyl polymer; the term refers to the precursor. It is sometimes important to ascertain the absence of unreacted vinyl monomer in the final product when the monomer is toxic or reduces the performance of the plastic. The following table gives some examples of vinyl and vinylidene polymers.
Monomer type | Monomer example | Example of resulting polymer |
---|---|---|
Vinyl | Vinyl chloride | Polyvinyl chloride (PVC) |
Vinyl fluoride | Polyvinyl fluoride (PVF) | |
Vinyl acetate | Polyvinyl acetate (PVAc) | |
Vinylidene | Vinylidene chloride | Polyvinylidene chloride (PVDC) |
Vinylidene fluoride | Polyvinylidene fluoride (PVDF) |
