Thermoplastic polymer among the following is

Options

A. Bakellite
B. Urea formaldehyde resin
C. Polysiloxanes
D. PVC

Answer

To determine which of the following is a thermoplastic polymer, we will analyze each option provided:

1. **Bakelite**:
- Bakelite is a type of phenol-formaldehyde resin.
- It is classified as a thermosetting polymer, meaning it hardens permanently when heated and cannot be remolded.
- **Conclusion**: Not a thermoplastic polymer.

2. **Urea Formaldehyde Resin**:
- Urea formaldehyde resin is also a thermosetting polymer.
- Similar to Bakelite, it cannot be reshaped once it has set.
- **Conclusion**: Not a thermoplastic polymer.

3. **Polysiloxanes**:
- Polysiloxanes are a class of silicone polymers.
- They are generally thermosetting polymers as well, which means they do not melt upon heating.
- **Conclusion**: Not a thermoplastic polymer.

4. **PVC (Polyvinyl Chloride)**:
- PVC is a widely used thermoplastic polymer.
- It can be melted and reshaped upon heating, making it a thermoplastic.
- **Conclusion**: This is a thermoplastic polymer.

**Final Answer**: The thermoplastic polymer among the options is **PVC (Polyvinyl Chloride)**.
