Name one polymer formed by step growth polymerisation. Give names of its monomers.

Explanation

To answer the question, we will follow these steps:

### Step 1: Understand Step Growth Polymerization
Step growth polymerization, also known as condensation polymerization, involves the reaction between two different monomers that leads to the formation of a polymer and the elimination of a small molecule, often water.

### Step 2: Identify a Polymer Formed by Step Growth Polymerization
One well-known polymer that is formed by step growth polymerization is **Dacron**.
