Define the term polymersation.

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Polymerization**: Polymerization is a chemical process where small molecules known as monomers combine to form larger molecules called polymers.

2. **Monomers**: Monomers are the basic building blocks of polymers. They are small, simple molecules that can link together in a repetitive manner.

3. **Formation of Polymers**: During polymerization, these monomer units undergo a series of chemical reactions to join together, resulting in the formation of long chains or networks of repeating units.
