Abstract: 1,147,684. Self-extinguishing thermoplastic compositions. BADISCHE ANILIN- & SODAFABRIK A.G. 19 July, 1966 [21 July, 1965], No. 32374/66. Headings C3C and C3P. A self-extinguishing composition consists of (a) a normally solid thermoplastic polymer or copolymer of styrene or substituted styrene which comprises at least 50% by wt. of the styrene or substituted styrene and less than 50% of one other olefinically unsaturated compound having intimately incorporated therewith (b) an organic bromide having a plurality of bromine atoms attached to carbon atoms and the bromine atoms making up more than 40% by wt. of the bromide, in such an amount that the composition has 0À1-5% wt. of bromine, and (c) 0À01-5% by wt. on (a) of a polymer consisting of repeating units of formula where R 1 is R 7 or XR 7 , R 7 is a C 1-6 aliphatic hydrocarbon, a phenylalkyl or phenyl radical which may be substituted by 1-5 chlorine atoms or a C 1-4 alkyl or alkoxy group and X is -O-, -CO- or -COO-; R 2 to R 6 are H, Cl or a C 1-4 alkyl or alkoxy group; and n is 3-200. The (a) polymer may be polystyrene or a copolymer of styrene and acrylonitrile. The (b) bromide may be hexabromocyclododecane or tris-(2,3-dibromopropyl) phosphate. The (c) polymer may be a polymerized diphenylmethane or ethylbenzene. The composition may be made by dissolving the three constituents in methylene chloride. The composition may also contain 3-10% of a foaming agent which is a volatile organic compound which does not dissolve the (a) polymer and has a boiling point below its softening point e.g. pentane, and may be foamed, e.g. in film form, using steam.
