Which of the following polymers contain`1,3,-`butadiene as one of the monomers?

Options

A. Nylon-6,6`
B. `PHBV`
C. Nylon`-2-` Nylon`-6`
D. Polychloroprene

Explanation

To determine which of the following polymers contains 1,3-butadiene as one of the monomers, we can follow these steps:

### Step 1: Understand the question
We need to identify polymers that have 1,3-butadiene as a monomer. 1,3-butadiene is a simple diene with the formula C4H6, which is often used in the production of various synthetic rubbers and other polymers.

### Step 2: Identify the polymers listed
Assuming we have a list of polymers to analyze (e.g., nylon 6,6, nylon 2,6, PHBV, and polychloroprene), we need to evaluate each one to see if 1,3-butadiene is a component.

### Step 3: Analyze each polymer
1. **Nylon 6,6**: This polymer is made from hexamethylene diamine and adipic acid. Neither of these monomers contains 1,3-butadiene.

2. **Nylon 2,6**: This polymer is made from glycine and amino carbonic acid. Again, there is no presence of 1,3-butadiene.

3. **PHBV (Poly(3-hydroxybutyrate-co-3-hydroxyvalerate))**: The monomers here are 3-hydroxybutanoic acid and 3-hydroxyvaleric acid. Neither of these monomers includes 1,3-butadiene.

4. **Polychloroprene**: This polymer, also known as neoprene, is made from chloroprene, which is derived from 1,3-butadiene. The structure of chloroprene includes the 1,3-butadiene unit.

### Step 4: Conclusion
Based on the analysis, the polymer that contains 1,3-butadiene as one of its monomers is **polychloroprene**.

### Final Answer
The answer to the question is **polychloroprene**.
