Synthetic polymer prepared by using caprolactam is known as

Options

A. terylene
B. teflon
C. nylon 6
D. Neoprene

Explanation

To solve the question regarding the synthetic polymer prepared by using caprolactam, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Caprolactam**:
Caprolactam is a cyclic amide (lactam) with the formula C6H11NO. It has a seven-membered ring structure that includes a nitrogen atom.

2. **Understand the Polymerization Process**:
Caprolactam undergoes a process called ring-opening polymerization. When caprolactam is heated in the presence of water, the ring opens up and the monomer units link together to form a long chain polymer.

3. **Temperature Conditions**:
The polymerization of caprolactam typically occurs at elevated temperatures, specifically between 533 K to 543 K.

4. **Formation of the Polymer**:
During the polymerization, multiple units of caprolactam (denoted as 'n' units) join together through amide linkages (-CONH-), leading to the formation of a synthetic polymer.

5. **Identify the Resulting Polymer**:
The polymer formed from caprolactam is known as Nylon 6. This is a type of polyamide, which is a category of polymers characterized by the presence of amide bonds.

6. **Conclusion**:
Therefore, the synthetic polymer prepared by using caprolactam is known as Nylon 6.

### Final Answer:
The synthetic polymer prepared by using caprolactam is known as **Nylon 6**.
