Abstract
Caprolactam is prepared by cleaving oligomers or polymers containing essentially the repeating unit --[--N(H)-(CH.sub.2).sub.5 --C(O)--]- in the presence of a catalyst at elevated temperatures by a process in which the cleavage is carried out in the liquid phase in the presence of a heterogeneous catalyst and of an organic solvent.
