description	Patente de Invenção: "DESPOLIMERIZAçãO DE POLIAMIDAS". A invenção rerfere-se a um processo para a despolimerização de uma ou mais poliamidas na presença de pelo menos um álcool alifático, a despolimerização ocorrendo com no máximo 40% em moles de catalisador. Tal processo propicia boa seletividade em relação aos componentes monoméricos de poliamidas. Além disso, tal processo produz um mínimo de correntes de despejo. 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.
