ABSTRACT:
Process for the depolymerization of one or more polyamides into its monomeric components in the presence of water by means of at least one alkali metal compound, at least one alkaline-earth metal compound or a combination thereof. The depolymerization takes place at a pressure of between 0.2 and 2.0 MPa, so that high conversions are achieved and the depolymerization reaction proceeds faster, even in the presence of a high content of cyclic oligomers.
