Teflon is polytetrafluroethylene (PTFE). This is a polymer with repeating chains of –(CF2-CF2)- in it.Teflon is prepared by the combination of a large number of tetrafluoroethylene molecules, without the elimination of any small molecule. Therefore, it is an example of addition homopolymer.
Polytetrafluoroethylene, better known as Teflon, is a synthetic fluoropolymer. A synthetic fluoropolymer is a fluorocarbon-based polymer with multiple strong carbon-fluorine bonds, making it highly resistant to solvents, acids and bases.
