Which of the following in not a condensation polymer?

Options

A. Nylon-66
B. PTFE
C. Dacron
D. Glyptal

Answer

To determine which of the following is not a condensation polymer, we need to understand the characteristics of condensation and addition polymers.

### Step-by-Step Solution:

1. **Define Condensation Polymers**:
- Condensation polymers are formed through a reaction where two or more monomers combine, resulting in the release of small molecules such as water (H2O) or ammonia (NH3) as by-products.

2. **Identify the Options**:
- We have the following options:
- A) Nylon 6X
- B) PTFE (Polytetrafluoroethene)
- C) Dechron
- D) Glyptyl

3. **Analyze Each Option**:
- **Option A: Nylon 6X**:
- Nylon is a well-known condensation polymer made from a diacid and a diamine, releasing water during polymerization.
- **Option B: PTFE (Polytetrafluoroethene)**:
- PTFE is made from the monomer tetrafluoroethene (CF2=CF2) through addition polymerization, where no small molecule is released.
- **Option C: Dechron**:
- Similar to nylon, Dechron is also a condensation polymer formed from a diacid and a diamine, releasing water.
- **Option D: Glyptyl**:
- Glyptyl is another condensation polymer formed through the reaction of monomers that release water.

4. **Determine the Non-Condensation Polymer**:
- From the analysis, options A, C, and D are all condensation polymers as they release water during their formation.
- Option B (PTFE) is the only one that is formed through addition polymerization, which does not release any small molecules.

5. **Conclusion**:
- Therefore, the answer to the question "Which of the following is not a condensation polymer?" is **Option B: PTFE (Polytetrafluoroethene)**.
