Caprolactam is the starting material for

Nylon 6,6 Nylon 6 Nylon 2,6 Dacron

Nylon 6

Nylon-6 or perlon is prepared by the polymerization of amino caproic acid at high temperatures. Caprolactam is first hydrolyzed with water to form amino acid which on heating undergoes polymerization to give nylon-6.
