Example of condensation polymer is?









Correct Answer :


Explanation :

Condensation polymers are any kind of polymers formed through a condensation reaction—where molecules join together—losing small molecules as byproducts such as water or methanol.

Terylene is a condensation polymer. The class of polyesters are formed by esterification reaction of a di-carboxylic acid with a diol. This reaction is called a condensation reaction because 2 molecules of water (H2O) are eliminated for every molecule of terephthalic acid that reacts with the diol.
