A non-catalytic method is provided for depolymerizing nylon-6 to produce e-caprolactam. The nylon, as a melt is continuously fed to a reaction zone together with superheated steam and undecomposed polymer melt is continuously withdrawn from the reaction zone together with steam and polymer decomposition products. Caprolactam is recovered from the polymer decomposition products.
