Abstract Ionizing radiation was employed to graft bromostyrene (BSy) onto poly(ethylene terephthalate) (PET) fabric. The fire‐retardant effect of the polymerized monomer on PET fabric was evaluated both by LOI tests and by DTA and TGA methods under conditions of controlled total combustion. The yields of HBr and BSy evolved during pyrolysis in the presence and absence of oxygen were determined. A linear correlation was found between ΔOI values and yields of HBr, and the implications of this finding are discussed. It is suggested on the strength of DTA and TGA results under total combustion conditions that the fire‐retardant effect of poly(bromostyrene) manifests itself mainly by a physical‐mode mechanism through a significant reduction in the release of flammable gases.
