Solution
The correct option is D Teflon Teflon is a chain-growth polymer manufactured by heating tetrafluoromethane with a free radical or persulphate catalyst at high pressures.
nCF2=CF2catalyst−−−−−−−−→Highpressure−[CF2−CF2−]n
Tetrafluoroethane Teflon
Whereas, nylon, bakelite and terylene are condensation polymers.
