Abstract Preliminary results are presented of a study concerning the mechanism of action of triphenyl phosphate (TPP) added to blends of poly(phenylene ether) (PPE) and high impact polystyrene (HIPS), 65/35 w/w. Comparison of effectiveness of TPP in increasing either the oxygen index or the nitrous oxide index of the polymeric blend, indicates that the fire retardant may act by a mixed gas‐condensed phase mechanism. The thermogravimetric behaviour of the fire retarded blend is compatible with this suggestion.
