Abstract

Polyamide 6 (PA-6) containing the fire retardants phosphorus oxynitride ((PON)_m) or phospham ((PN₂H)_n) was exposed to ⁶⁰Co-γ-rays (absorbed dose: 1.0–4.0 MGy). The irradiation led to crosslinking of the polymer which caused an increase in the char yield and a decrease in the flammability of the polymer. The combustion behavior was strongly affected by irradiation: dripping was totally prevented in the case of system PA-6/(PN₂H)_n and strongly retarded in the case of system PA-6/(PON)_m. The thermal stability of the system PA-6/(PN₂H)_n decreased with increasing absorbed dose whereas the thermal stability of the system PA-6/(PON)_m did not change.
