Which of the following is made to heat tetrafluoroethene on high pressure with free radical or percussive catalyst?
Teflon
Teflon is polytetrafluoroethylene (PTFE). It is made by heating tetrafluoroethene (CF2=CF2) under high pressure with a free-radical or persulphate catalyst (written here as "percussive").
\(n\,\text{CF}_2=\text{CF}_2 \rightarrow (-\text{CF}_2-\text{CF}_2-)_n\)
Teflon resists chemicals and heat well and is used in non-stick cookware coatings and gaskets.
Polyester (such as Terylene) is a condensation polymer of a diol and a dicarboxylic acid, and Nylon 6 is made from caprolactam, so neither comes from tetrafluoroethene. (The source prints "Nylon 6" twice among the options.)
Hence, the polymer made this way is Teflon.
