Abstract: The invention relates to a fire-resistant copolymer of bromostyrene and another monomer, preferably acrylonitrile, and a process for preparing same by emulsion polymerization to produce copolymers having 95 to 25 weight percent bromostyrene, the balance being the second monomer. The resulting copolymers have a high bromine content in the range 20 to 44 weight percent and may be used as such as a flame-resistant plastics material or admixed with other plastics such as the polyolefins to impart fire-resistance to the mixture. The copolymers produced exhibit good mechanical properties and fire-resistance values.
