Hu, Y., Fan, W.C., Wang, Q., Akutsu, Y. and Tamura, M., 1988. Study On Gas Phase Long-Lived Radicals In Modified Polyurethane Combustion And Decomposition. AOFST 3
ABSTRACT
Combustion and decomposition properties in polyurethane modified by flame retardant were investigated using the electron spin resonance (ESR) spin-trapping technique and thermogravimetry (TG), The long lived gas phase radicals in combustion and decomposition products of polyurethane were studied. It was shown that the concentration of radicals in combustion was reduced by adding hexachlorotriphosphazene containing chlorine, and also thermal decomposition in polyurethane was accelerated by phosphazene.
