Flame retardant polystyrene plastic compositions

摘要

Disclosed are plastic compositions comprising (i) polystyrene; (ii) a bis-phenoxy compound of the formula wherein alkylene is a straight chain carbon group having 1 to 6 carbon atoms; (iii) a poly (brominated phenylene oxide); and (iv) an enhancing agent. Also described is a flame retardant additive composition for polystyrene plastic compositions comprising (i) said bis-phenoxy compound, (ii) said poly (brominated phenylene oxide), and (iii) said enhancing agent.
