Abstract: A self-extinguishing composition consists of (a) a normally solid thermoplastic homopolymer or copolymer of styrene which may be substituted by alkyl groups in the nucleus or side chain and which contains more than 50% by wt. of styrene or the substituted styrene having intimately incorporated therewith (b) an organic bromide having a plurality of bromine atoms attached to the carbon atoms and the bromine atoms constituting more than 40% of the bromide, in such an amount that the composition has a bromine content of 0.1-5%, and (c) 0.01-5% of (a) of a compound of formula where RA and RB are a phenyl radical which may be substituted by at least one C1- 3 aliphatic hydrocarbon radical, a C1- 4 alkoxy radical, Cl or Br; R1 and R2 are H, Cl, Br, a C1- 6 aliphatic hydrocarbon radical or cyclohexyl; R3 and R4 are Cl, Br, cyano, nitro, a C1- 6 aliphatic hydrocarbon radical or phenyl. The (a) polymer may be polystyrene and/or a copolymer of styrene and acrylonitrile. Compound (c) may be 2,3-diethyl - 2,3 - diphenylbutane; 2,2,3,3 - tetraphenylbutane or 2,3 - dimethyl - 2,3 - di - p - tolylbutane. The bromide (b) may be hexabromododecane, tris - (2,3 - dibromopropyl)-phosphate or tetrabromoethane. The composition may be made by dissolving the three components in methylene chloride. The composition may also contain a foaming agent, e.g. pentane, and may be formed into a foamed sheet.
