Differentiate between the molecular structures and behaviour of thermoplastic and thermosetting polymers. Give one example of each type

Explanation

### Step-by-Step Solution:

**1. Molecular Structure:**
- **Thermoplastic Polymers:**
- The molecular structure of thermoplastics is primarily linear or slightly branched. This means that the polymer chains are arranged in a straight line or have minor branches off the main chain.
- Example: Polyethylene (PE) and Polyvinyl Chloride (PVC) are common thermoplastics.

- **Thermosetting Polymers:**
...
