ABSTRACT:
High impact thermoplastic polymers such as the styrenic based polymers, ABS and high impact polystyrene, are rendered fire retardant by the incorporation in the polymer of a mixture of a diadduct of hexahalocyclopentadiene and decabromodiphenyl oxide. The fire retardance of the compositions can be further enhanced by the incorporation therein of a metallic compound, particularly a compound of aluminum, zinc, arsenic, antimony or bismuth. A preferred metallic compound is antimony oxide.
