What is condensation polymerisation? Write with an example.

Explanation

If evaporation is carried out in a closed container then the vapour remains in contact with the surface of the liquids These vapour molecules are in continuous random motion during which they colide with each other and also with the walls of the container.As the collision is inelastic they lose their energy and as result the vapour returns back to liquids state. This process is called as condensation'
