Abstract

La invencion se refiere al compuesto caprolactama que se prepara por desdoblamiento de los oligomeros o polímeros que contienen esencialmente la unidad repetidora -[-N(H)-(CH2)5-C(O)-]- en presencia de un catalizador a temperaturas elevadas, mediante un proceso en el que el desdoblamiento se lleva a cabo en fase líquida, en presencia de un catalizador heterogéneo y de un solvente orgánico.
