Use

ε-Caprolactam is used as a monomer in the preparation of synthetic fibers of the polyamide as well as a solvent for high molecular weight polymers. It is also used in coatings and plasticizers. Further, it is used as a cross linking agent for polyurethanes. In addition to this, it is used to prepare nylon-6, which finds application in fibers and plastics.
