ABSTRACT:
The flame resistance of blends of polyphenylene ether resin and high impact polystyrene is upgraded by the inclusion of a combination of a polybrominated 1,4-diphenoxybenzene and antimony oxide. The resulting composition exhibits good thermal stability and is more resistant to undergoing juicing and blooming in comparison with the use of polybrominated diphenyl oxides.
