✦ Synopsis

Two commercial flame retardant FR additives, a brominated phosphate esterrantimony trioxide mixture and a magnesium hydroxide were added up to 30 and 60% by weight to polypropylene matrix, respectively. The impact behaviour of the PPrFR Ž . composites were studied by the Charpy impact test and the impact fracture toughness G measurement. As the amount of FR c increases, the impact properties decreased accordingly. Such behaviour is strongly related to the morphologies and was Ž . investigated by means of scanning electron microscopy SEM .

The effect of tetrabromobisphenol A diallyl ether (TBBA-DAE) on the flame retardancy of high impact-strength polystyrene (HIPS) was studied and compared with that of tetrabromobisphenol A (TBBA). Experimental results showed that the flame retardancy of TBBA-DAE was superior to that of TBA by thermom
