Caprolactum is a monomer of nylon-6.
$\underset{\text{heat}}{\overset{{\text{H}}_{\text{2}}\text{O}}{\to }}\underset{\begin{array}{c}\text{amino}\text{caproic}\\ \text{acid}\end{array}}{H_{2}N-{(-C{H}_2)}_5-COOH}$ $\underset{-H_{2}O}{\overset{Heat}{\to }}\underset{nylon-6}{{\left[-NH-{(C{H}_2)}_5-\stackrel{O}{\stackrel{||}{C}}-\right]}_n}$
