| 摘要 |
A flame retardant polymeric composition comprising a monoalkenyl aromatic polymer having polymerized therein from about 5 to about 25 mole percent of an imide having appended, to the nitrogen atom, a bromine substituted aliphatic hydrocarbon radical. The composition is formed by melt blending a copolymer of a monoalkenyl aromatic monomer and an ethylenically-unsaturated anhydride with a brominated, primary aliphatic amine. |
