Abstract
A simplified mechanism for the depolymerization of nylon-66 and nylon- 6 mixtures via the ammonolysis route is proposed here. The mechanism i ncludes the amide link breakage and amide end dehydration (nitrilation ) reactions, plus the ring addition and ring opening reactions for cyc lic lactams in nylon-6. On the basis of the proposed mechanism, a kine tic model has been developed for the ammonolysis of nylon mixtures. Mo del predictions and results from parametric studies are presented and discussed.
