Explain addition and condensation polymers.

1. Addition polymers- The polymers which are formed by combination of chemical bond formation of simple organic monomers having double bond are called addition polymer.

Ex- Polystyrene is an addition polymer which is prepared from styrene.

2. Condensed polymers- When two different types of simple monomers combine with one another by condensed polymerisation and give polymers after removal of molecules like water, ammonia or alcohol are called condensed polymers.

Ex- Nylon6,6 is a condensed polymer which is obtained from hexamethylene diamine and adipic acid.
