Red phosphorus contained in non-irradiated polyamide-6 at concentrations up to 12.5 does not significantly improve the fire resistance of the polymer. It weakens the thermal stability of the polymer as reflected by a decrease in the onset temperature

Cross-linking of polymers is frequently presumed to enhance the thermal stability of polymer systems. Methyl methacrylate has been reacted with divinylbenzene and styrene with various dimethacrylates. These systems have been characterized by gel cont

The fire retardant action of red phosphorus in nylon 6 was im proved by co-addition of ferric/ferrous oxides. It was found that the activity of Fe oxides depends on the product grade. Polymer formulations, non-ignitable in air were obtained by co-add

Polyisoprene and polychloroprene have been cross-linked either in solution or in solid state using free radical initiators. In the comparable experimental conditions higher cross-linking density was observed in the solid state process. Independent of

Polyamide 6 (PA-6) containing the fire retardants phosphorus oxynitride ((PON) m ) or phospham ((PN 2 H) n ) was exposed to 60 Co-γ-rays (absorbed dose: 1.0–4.0 MGy). The irradiation led to crosslinking of the polymer which caused an increase in t
