Question
Which of the following is made to heat tetrafluoroethene
on high pressure with free radical or percussive catalyst?Solution
Polytetrafluoroethylene (PTFE), commonly known as Teflon , is made by heating tetrafluoroethylene under high pressure with a free radical initiator or a peroxide catalyst. This process involves polymerization, where the monomers (tetrafluoroethylene) are converted into a polymer (PTFE) using these catalysts to initiate and propagate the reaction.
