Question

Teflon is an example of polymer which is a/an

• A. polyamide
• B. addition Ploymer
• C. polyster
• D. formaldehyderesin

Answer 1

Answer: (B)

TEFLON - It is an addition polymer prepared by heating tetrafluoroetane with a free radical.
$nC{F}_2=C{F}_2\underset{Highpressure}{\overset{Catalyst}{\to }}-[C{F}_2-C{F}_2-{]}_n$
Tetrafluoroetane Teflon
POLYAMIDE - These are polymers possessing amide linkage and Teflon doesn't contain any amide linkage.
POLYSTER - These are polycondensation products of dicarboxylic acids and diols.
FORMALDEHYDE RESIN - It can refer to many formaldehyde polymers such as melamine formaldehyde, urea formaldehyde, phenol formaldehyde.
