Abstract: 1,166,290. Self-extinguishing thermoplastic compositions. BADISCHE ANILIN- & SODAFABRIK A.G. 29 Dec., 1966 [5 Jan., 1966], No. 58124/66. Headings C3C and C3P. A self-extinguishing thermoplastic composition having a bromine content of at least 0.1% by wt. consists of a thermoplastic polymer which contains more than 50% by wt. of styrene or a nuclear alkyl-substituted styrene and a polymer of butadiene and/or isoprene which has at least 50% of its base units combined by 1,2-linkages and which is brominated to a content of 40-75% by wt. of bromine. The styrene polymer may be polystyrene. In an example, a mixture of styrene and acrylonitrile was polymerized in an aq. mixture of benzoyl peroxide, barium sulphate and the brominated polyisoprene. In comparative examples brominated polymers of butadiene and isoprene having 1,4-linkages were used. Porous polymers are produced in the examples by polymerizing styrene in an aq. mixture of (A) polyvinylpyrrolidone and sodium pyrophosphate; (B) barium sulphate; or (C) a copolymer of N-vinyl-pyrrolidone and methyl acrylate, sodium pyrophosphate and a polymer of diisopropylbenzene; and pentane, benzoyl peroxide and the brominated polybutadiene and the polystyrene beads produced are preexpanded in steam and then formed into blocks by further steam treatment.
