Question

Condensation polymer differs from addition polymers:

Answer 1

Hint :To answer this question we just need to have some basic idea about polymerization and all and some basic idea of condensation polymer and addition polymer or polymerization you have then it is well and good. Everything you will get to know in this answer. I will explain it briefly in the below section.

Complete Step By Step Answer:
It is a method of combining small molecules to form large molecules or we can say that macromolecule. These small molecules are monomers that serve as the building blocks of polymers. Now the difference between condensation polymerization and addition polymerization is that in condensation polymerization, the polymers are formed by the condensation of one or more than one monomers which results in the formation of small molecules or by products such as water, ammonia, etc. In addition polymerization no such by-products are formed. They are formed just by the addition of the monomers. Examples of condensation polymerization are nylon- $ 6 $ , nylon- $ 6,6 $ , terylene (Dacron), etc. Now, some examples of addition polymerization are the formation of polypropylene $ \left( {{{\left( {{C_3}{H_6}} \right)}_n}} \right) $ from propene $ \left( {{C_3}{H_6}} \right) $ and polythene $ \left( {{{\left( {{C_2}{H_4}} \right)}_n}} \right) $ from ethene $ \left( {{C_2}{H_4}} \right) $ , etc.

Note :
There are two types of addition polymerization and they are homopolymers (which are formed by the addition of single polymeric species). For example, polythene $ \left( {{{\left( {{C_2}{H_4}} \right)}_n}} \right) $ and other one is copolymers (which are formed by the by addition polymerization from two different monomers). For example, Buna-N, Buna-S, etc.
