Teflon is a polymer of

Teflon is polytetrafluoro ethylene and it is prepared from tatrafluoro ethylene by heating under pressure in the presence of ammonium peroxydisulphate. n \mathrm{CF}}_{2}= \mathrm{CF}}_{2} \frac{\left(\mathrm{NH}_4\right)_2 \mathrm{~S}_2 \mathrm{O}_8}{\text{ high pressure }}\left(\mathrm{CF}}_{2}- \mathrm{CF}}_{2}\right)_n It is chemically inert and heat resistant polymer.
