What is the difference between two notations : nylon - 6 and nylon - 66 ?

Explanation

To understand the difference between nylon-6 and nylon-6,6, we need to analyze the structure and composition of each polymer.

### Step 1: Understanding Nylon-6
Nylon-6 is a synthetic polymer made from a single type of monomer called caprolactam.

- **Monomer Composition**: Caprolactam has a molecular structure that contains 6 carbon atoms (C6).
- **Formation**: When caprolactam undergoes polymerization, it forms a long chain of repeating units, resulting in nylon-6.
