Which one of the following polymers is prepared by addition polymerisation?
A
Nylon-66
B
Novolac
C
Dacron
D
Teflon
Detailed Solution
Teflon is prepared by addition polymerisation of tetrafluoroethene:
$nCF_2=CF_2 \xrightarrow[high\ pressure]{catalyst} -(CF_2-CF_2)_n-$
Nylon-66, Novolac and Dacron are prepared by condensation polymerisation.
