Besides the monomer some minor but characteristic volatile thermal decomposition products are observed pyrolysing polyamide-6 in the presence of PVC. It was proven that hydrogen chloride thermally eliminated from PVC gives rise to facilitated depolymerization of PA-6, partial hydrolysis of the amide groups, evolution of 6-chlorohexanenitrile, and promoted nitrile and vinyl end group formation. A mechanism is proposed for the advance of these reactions by hydrogen chloride. Depolymerization and hydrolysis are initiated at a considerably lower temperature in the presence of PVC, at the temperature of the hydrogen chloride elimination from the latter. Studying the aspect of high temperature decomposition it was observed that the presence of PVC severely increased the hydrogen cyanide evolution from PA-6 at 900°C.
