Which of the following is a branched polymer?

Options

A. Low density polymer
B. Polyester
C. high density polymer
D. nylon

Answer

To determine which of the given options is a branched polymer, we need to analyze each option based on the characteristics of branched and linear polymers.

### Step-by-Step Solution:

1. **Understanding Polymer Types**:
- **Branched Polymers**: These have a complex structure with side chains attached to the main chain. They typically have lower density due to the presence of branches.
- **Linear Polymers**: These have a straight chain structure without branches, resulting in a higher density.

2. **Analyzing the Options**:
- **Option A: Low Density Polymer (LDP)**: This type of polymer is known for its branched structure. Examples include polyethylene (LDPE), which is highly branched.
- **Option B: Polyester**: This is a type of high-density polymer that has a linear structure. Therefore, it is not branched.
- **Option C: High Density Polymer (HDP)**: Similar to polyester, HDPs have a linear structure and are not branched. Examples include polyethylene (HDPE).
- **Option D: Nylon Polymers**: Nylon is also a high-density polymer with a linear structure, thus not branched.

3. **Conclusion**:
- From the analysis, the only option that represents a branched polymer is **Option A: Low Density Polymer**.

### Final Answer:
The branched polymer among the given options is **Low Density Polymer (LDP)**.
