The pyrolysis of nylon 6 has been shown to proceed by a first‐order process to yield ε‐caprolactam as the primary product. This degradation has an energy of activation of approximately 46 kcal/mole which would seem to indicate the involvement of a homolytic process. Inclusion of organobromine compounds such as hexabromobiphenyl and dodecabromopentacyclo [5·3·0·0 2,6 ·0 3,9 ·0 4,8 ]decane catalyzed the pyrolysis but did not significantly alter the nature of the degradation products. Because of this, simple organobromine compounds are not good candidates for utilization as flame retardants for nylon 6.
