  • Patent number: 8575257
    Abstract: A flame retardant brominated rubber polymeric composition, wherein the composition can include ethylene propylene ethylidene norbornene rubber polymer and from 12 weight percent to 55 weight percent of bromine covalently bonded thereto. The method can include dissolving a liquid ethylene propylene ethylidene norbornene rubber polymer in hexane with myrcene, forming the composition. The method can include dissolving ethylene propylene ethylidene norbornene rubber polymer in hexane, forming a solution, and adding bromine, or blending N-bromo-succinimide into the solution, forming a suspension. The method can include heating the suspension and stifling the suspension until all bromine in the N-bromo-succinimide has reacted with the ethylene propylene ethylidene norbornene rubber polymer, forming the composition as a solid in a liquid. The method can include removing the liquid from the solid, and flashing off the hexane from the liquid to extract the composition.
