Abstract
Preliminary results are presented of a study concerning the mechanism of action of triphenyl phosphate (TPP) added to blends of poly(phenyle ne ether) (PPE) and high impact polystyrene (HIPS), 65/35 w/w. Compari son of effectiveness of TPP in increasing either the oxygen Index or t he nitrous oxide index of the polymeric blend, indicates that the fire retardant may act by a mixed gas-condensed phase mechanism. The therm ogravimetric behaviour of the fire retarded blend is compatible with t his suggestion.
