Abstract
The distribution of the temperature and the morphology of the charred material formed in the combustion of blends of poly(phenylene ether) ( PPE) with high impact polystyrene (HIPS), carried out in the UL94 test , were examined. The effect of the fire retardant triphenyl phosphate Is shown to be the decrease of time of burning, of temperature of the specimen and of zone involved in combustion, without apparent modifica tion of the char structure. Hypothesis on gas and condensed phase fire retardant mechanisms are discussed.
