Deploymerization of polyamides

Process for the depolymerization of one or more polyamides into its monomeric components in the presence of water by means of an alkali (alkaline-earth) metal compound, the depolymerization taking place at a pressure of between 0.2 and 2.0 MPa, so that high conversions are achieved and the depolymer...

Zusammenfassung:	Process for the depolymerization of one or more polyamides into its monomeric components in the presence of water by means of an alkali (alkaline-earth) metal compound, the depolymerization taking 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 high contents of cyclic oligomers.
