Polymeric compositions possessing improved flammability resistance

Polymeric compositions possessing improved flammability resistance

A flame retardant polymeric composition comprising a monoalkenyl aromatic polymer having polymerized therein from 5 to 25 mole percent of an imide having appended, to the nitrogen atom, a bromine substituted aliphatic or brominated-arcmatic substituted aliphatic hydrocarbon radical. The compositior...

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