Ten tetrabrominated bisimides of which eight were novel were tested as flame‐retardant additives. They were prepared from corresponding bisimides by the addition of bromine. Structural properties and related thermal characteristics of these brominated compounds were determined. Flame‐retardant properties of tetrabrominated bisimides were tested on high‐impact polystyrene, containing various amounts of brominated bisimides, according to ASTM‐D‐3801, “Standard Test Method for Measuring the Comparative Extinguishing Characteristics of Solid Plastics in a Vertical Position,” and DIN‐51960, “Testing of Organic Floor Coverings Assessment of Flammability.” It was observed that tetrabrominated bis‐imides had improved flame resistance of high‐impact polystyrene. In addition, thermoxi‐dative stability of novel three bisimides, 04, 14 , and 05 , were compared with the others. © 1996 John Wiley & Sons, Inc.
