उत्तर १
Chemically, Teflon is polytetrafluoroethylene. The monomer used in the preparation of Teflon is tetrafluoroethylene, (CF2 = CF2) which is a gas at room temperature.
Tetrafluoroethylene is polymerized by using free radical initiators such as hydrogen peroxide or ammonium persulphate at high pressure.
\[\ce{\underset{Tetrafluoroethene}{nCF2 = CF2} ->[Polymerization][Peroxide] \underset{Teflon}{-[CF2 - CF2]}-_n}\]
