Which one of the following polymers is prepared by condensation polymerization?

Options

A. Styrene
B. Nylon-6,6
C. Teflon
D. Rubber

Answer

To determine which polymer is prepared by condensation polymerization, we can follow these steps:

### Step 1: Understand Condensation Polymerization
Condensation polymerization is a type of polymerization where two or more monomeric units combine to form a polymer, releasing small molecules such as water or alcohol in the process.

### Step 2: Analyze the Given Options
We need to evaluate the options provided to identify which polymer is formed through condensation polymerization. The options include:
- Styrene
- Nylon 66
- Teflon
- Rubber

### Step 3: Evaluate Each Option
- **Styrene**: This is a monomer that undergoes addition polymerization to form polystyrene, not condensation polymerization.

- **Nylon 66**: This polymer is synthesized from hexamethylenediamine and adipic acid. The reaction involves the elimination of water molecules, indicating that it is formed through condensation polymerization.

- **Teflon**: Teflon is made from the polymerization of tetrafluoroethane, which is an example of addition polymerization.

- **Rubber**: Natural rubber is primarily composed of isoprene, which also undergoes addition polymerization.

### Step 4: Conclusion
Based on the analysis, the polymer that is prepared by condensation polymerization is **Nylon 66**.

### Final Answer
**Nylon 66** is the polymer prepared by condensation polymerization.
