ABSTRACT:
The present invention relates to fire retardant polymer compositions obtained by the blending of monomeric N-tribromophenylmaleimide, as a fire retardant additive with a polymer. The preferred amount of bromine in the composition is above 0.5% by weight thereof. The polymer is selected from styrenic polymers and copolymers, polyolefine, rubbers, epoxy resins, plasticized PVC and polyurethane. If desired, one or more additional fire retardant(s) may be incorporated in the composition. Optionally, synergistic fire retardant additives such as antimony oxide, or organo-phosphorus compounds are also incorporated. The flame retardant polymer compositions have improved properties compared with those obtained with known flame retardant reagents. It was also unexpectedly found that the fire retardant additive provides to the polymer composition stability against ultraviolet light irradiation.
