  Differentiate between addition and condensation polymers based on mode polymerization. Give one example of each.                                                                                                                                                                                                     3

Answer:

   

Addition polymerization	Condensation polymerization
1. The polymers which are formed by repeated addition of monomers to the polymer chain,	A large number of monomers combines with the loss of simple molecules like etc. to form a polymer.                                                                                      1
2. Polymer, have same molecular formula of the repeating structural unity as that of starting material.	Polymers have molecular formula of the repeating structure unit different from the starting monomer.   1
3. e.g., Polythene	eg. Nylon-66                                                                              1
