Explanation:

Caprolactam is the starting material for Nylon 6.

Nylon 6 is a synthetic polymer made of repeating units of ε-Caprolactam. Caprolactam is a cyclic amide with the chemical formula (CH₂)₅C(O)NH.

It is produced by the reaction of cyclohexanone with ammonium sulfate, followed by a series of purification steps. The purified caprolactam is then used in the polymerization reaction to produce Nylon 6.

During the polymerization reaction, caprolactam molecules are opened up and linked together through amide bonds to form long chains of Nylon 6.

These chains can then be further processed into fibers, films, and other forms used in various applications such as textiles, carpets, and packaging.

In summary, caprolactam is the starting material for Nylon 6, a versatile and widely used synthetic polymer.
