Question

TestHub · Accepted Answer

Teflon is the commercial name for polytetrafluoroethylene (PTFE).

The monomer of Teflon is tetrafluoroethylene, which has the chemical formula $C F_{2} = C F_{2}$ .

Since all the hydrogen atoms in the ethylene monomer are replaced by fluorine atoms, Teflon is a fully fluorinated polymer.

PVC (polyvinyl chloride) contains chlorine and hydrogen, neoprene contains chlorine and hydrogen, and Buna-S is a hydrocarbon polymer containing only carbon and hydrogen.
