Giving one example of each of :
(i) addition polymers
(ii) condensation polymers
(iii) copolymers.

Explanation

To answer the question of providing one example for each of the types of polymers: addition polymers, condensation polymers, and copolymers, we can break it down step by step.

### Step-by-Step Solution:

1. **Addition Polymers:**
- **Definition:** Addition polymers are formed by the addition of monomer units without the loss of any small molecules. The double bonds in the monomers open up to form long chains.
- **Example:** Polyvinyl Chloride (PVC)
- **Monomer:** Vinyl Chloride (C2H3Cl)
