Teflon - Thermally stable cross-linked polymer of phenol and formaldehyde

Vedclass · Answer

(B) The correct answer is $B$. $Teflon$ is a polymer of tetrafluoroethylene $(CF_2=CF_2)$,which is a thermoplastic. Phenol and formaldehyde form $Bakelite$,which is a cross-linked thermosetting polymer. $Terylene$ is indeed a condensation polymer of terephthalic acid and ethylene glycol. $Perspex$ (or $PMMA$) is a homopolymer of methyl methacrylate. $Synthetic$ $rubber$ (like $Buna-S$) is a co-polymer of $1,3-butadiene$ and styrene.
