Write the structure of monomers used for getting the following polymers:
Glyptal

Explanation

To determine the monomers used to produce the polymer Glyptal, we need to identify the two key components involved in its formation.

### Step 1: Identify the first monomer - Ethylene Glycol
The first monomer used to create Glyptal is **ethylene glycol**. The chemical structure of ethylene glycol can be represented as follows:

- **Structure of Ethylene Glycol**:
\[
\text{HO-CH}_2-\text{CH}_2-\text{OH}
