Question
Write preparation, properties and uses of Teflon.
✓
Answer
Teflon is polytetrafluoroethylene. The monomer used in preparation of teflon is tetrafluoroethylene, $(CF_2 = CF_2)$ 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.
Properties:
Properties:
- Telflon is tough, chemically inert and resistant to heat and attack by corrosive reagents.
- C – F bond is very difficult to break and remains unaffected by corrosive alkali, organic solvents.
Uses : Telflon is used in making non-stick cookware, oil seals, gaskets, etc.
