Abstract
Abstract New flame-retarded rubber and plastic compositions are disclosed which are economical to produce and which exhibit increased flame-retardance, improved mechanical properties and reduced toxicity. Generally, these new compositions comprise a copolymer of acrylonitrile-butadiene rubber or a terpolymer of acrylonitrile, butadiene and styrene, a bromine- or chlorine-containing organic fire-retardant additive, and an iron oxide.
