Depolymerization of polyamides |
| abstract |
One or more polyamides can be depolymerized in the presence of at least one nitrogen-containing compound. The depolymerization takes place at a pressure between about 0.5 and about 5 atm. The polyamide may be in the form of carpet waste or other heterogeneous form. Advantages include better selectivity towards the polyamide monomeric components and use of low pressure equipment to effect depolymerization. |
