| titleOfInvention | Flame retardant polymer compositions |
| abstract | The present invention relates to fire retardant polymer compositions possessing a non-linear structural configuration resulting by the reaction of N-tribromophenylmaleimide, with or without comonomer, with a preformed backbone polymer, in which the bromine content is above 1.2% by weight bromine. The polymer is selected from polystyrene, polyolefins, polyamides, rubbers, polyesters, acrylics, polymeric dienes and mixtures or copolymers thereof. The comonomer present with the N-tribromophenyl. maleimide is selected from the group consisting of acrylonitrile, styrene and vinyl chloride. According to the invention the non-linear structural configurations are obtained either by grafting or crosslinking of the N-tribromophenylmaleimide onto the preformed backbone polymer in the presence of free radicals producing means. Optionally, synergistic fire retardant additives such as antimony oxide are incorporated in the compositions. The preferred compositions will contain above 4% by weight of the total resin present in the compositions. The flame retardant polymer compositions have improved properties compared with those obtained with known flame retardant reagents. |
