Polymers used in unbreakable glass is

Options

A. PMMA
B. Poly vinyl cyanide
C. PVC
D. PVP

Answer

To determine the polymer used in unbreakable glass, we can analyze the options provided:

1. **Identify the polymers listed**:
- PMMA (Polymethylmethacrylate)
- Polyvinyl cyanide
- PVC (Polyvinyl chloride)
- PVP (Polyvinyl pyrrolidone)

2. **Understand the applications of each polymer**:
- **PMMA (Polymethylmethacrylate)**: This polymer is commonly used for making unbreakable glass, bulletproof jackets, and plexiglass. It is known for its clarity and impact resistance.
- **Polyvinyl cyanide**: This polymer is primarily used in making winter clothing, such as sweaters, and is not related to glass.
- **PVC (Polyvinyl chloride)**: This polymer is mainly used for making pipes and is not suitable for glass applications.
- **PVP (Polyvinyl pyrrolidone)**: This polymer is utilized in making antiseptic drugs and has no relation to glass.

3. **Conclusion**:
- Based on the applications of the polymers, PMMA is the polymer specifically used for making unbreakable glass.

Thus, the correct answer is **PMMA (Polymethylmethacrylate)**.
