Depolymerization of polyamides

The invention relates to a process for depolymerising one or more polyamides in the presence of at least an aliphatic alcohol, the depolymerisation taking place with at most 40 mol. % catalyst. This process provides good selectivity towards the monomeric components of polyamides. This process moreov...

Beschreibung
Zusammenfassung:	The invention relates to a process for depolymerising one or more polyamides in the presence of at least an aliphatic alcohol, the depolymerisation taking place with at most 40 mol. % catalyst. This process provides good selectivity towards the monomeric components of polyamides. This process moreover causes as few waste streams as possible.
