ABSTRACT:
Polymeric materials are rendered fire retardant by incorporating therein a Diels-Alder adduct of a halogenated cyclopentadiene and bicyclononadiene. The fire retardance of the compositions can be further enhanced by the incorporation therein of a metallic compound, particularly a compound of antimony, arsenic or bismuth. A preferred metallic compound is antimony oxide.
