Solution

The correct option is D Teflon
Teflon is an addition polymer. Condensation polymers are any kind of polymers formed through a condensation reaction where molecules join together losing small molecules as by-products such as water or methanol, e.g., Nylon - 6, 6, Dacron (or Terylene) and Glyptal etc.
It can be seen from the reactions:
For Nylon-66

For terylene or Dacron

For Glyptal
It can been seen that in all the above three reactions, water molecule is lost to form the product. Hence, there three products are condensation polymers.



In the reaction of Teflon, it can be clearly seen that it is an addition product.
