FIRE RETARDANT HIGH IMPACT STYRENIC POLYMER COMPOSITIONS

摘要

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 a halogenated cyclopentadiene, decabromodiphenyl oxide and a polyunsaturated cyclic compound. 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.
