Name one thermosetting and one thermoplastic polymer.

Explanation

To answer the question, we need to identify one thermosetting polymer and one thermoplastic polymer. Let's break it down step by step:

### Step 1: Understand the Definitions
- **Thermosetting Polymers**: These are polymers that undergo a chemical change when heated, resulting in a rigid structure that cannot be remolded or melted. They are characterized by cross-linked structures that become infusible upon heating.

- **Thermoplastic Polymers**: These are polymers that can be repeatedly softened and reshaped upon heating. They have linear or slightly branched structures that allow them to be remolded multiple times.
