description This invention provides a flame retardant additive composition which comprises at least one glow suppressant and at least one brominated flame retardant. The glow suppressant is about 0.5 wt % or more of the flame retardant additive composition, based on the total weight of the flame retardant additive composition. The brominated flame retardant contains aromatically-bound bromine and is selected from a) a brominated anionic styrenic polymer having a number average molecular weight of about 750 to about 7500, and/or a bromine content of about 60 wt % to about 77 wt %, b) a brominated anionic chain transfer vinyl aromatic polymer which contains about 70 wt % or more bromine, or a mixture of any two or more of these. Also provided are flame retarded polyolefin compositions that contain at least one glow suppressant and a brominated flame retardant.
