Which one is biodegradable polymer?

Options

A. Nylon-2-Nylon-6
B. Nylon-6,6
C. Nylon-6
D. All of these

Answer

To determine which of the given options is a biodegradable polymer, we can follow these steps:

### Step 1: Understand the Definition of Biodegradable Polymers
Biodegradable polymers are those that can be broken down by microorganisms, such as bacteria, into smaller, non-toxic components. This process helps reduce pollution and waste.

### Step 2: Analyze the Given Options
The options provided are:
- Nylon 2
- Nylon 6
- Nylon 6,6
- Nylon 6
- All of these

### Step 3: Identify the Characteristics of Each Polymer
1. **Nylon 2**: Known to be biodegradable as it can be decomposed by microbial action.
2. **Nylon 6**: Generally not considered biodegradable; it is more resistant to microbial degradation.
3. **Nylon 6,6**: Similar to Nylon 6, it is also not biodegradable.
4. **Nylon 6 (repeated)**: Again, this is not biodegradable.
5. **All of these**: This option cannot be correct since not all listed nylons are biodegradable.

### Step 4: Conclusion
From the analysis, the only biodegradable polymer among the options is **Nylon 2**.

### Final Answer
The biodegradable polymer is **Nylon 2**.
