摘要：

Polyamide 6 (PA-6) containing the fire retardants phosphorus oxynitride ((PON)(m)) or phospham ((PN2H)(n)) was exposed to Co-60-gamma-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. (C) 1999 Elsevier Science Ltd.
