    Notes: Commercial acrylonitrile butadiene styrene (ABS) polymers are among the most flammable of the currently available range of thermoplastic materials. In addition to having a rather low limiting oxygen index (LOI) value in the range 18.3-18.8, ABS polymers also produce compious amounts of smoke and hazardous gases when burnign in the air. In a recent study directed towards preparing and evaluating compounds which would simultaneously reduce the flammability and smoke produced from burning thermoplastic polymers, a synergistic flame-retarding/smoke-suppressing system based on organoiron compounds has been produced, which when properly compounded into ABS/PVC [poly(vinyl chloride)] blends more than doubles the LOI nad at the same time reduces smoke production significantly.

    Iron-containing organometallic compounds as flame-retarding/smoke-suppressing additives for semi-rigid poly(vinyl chloride) (1990)
    New York, NY [u.a.] : Wiley-Blackwell
    Applied Organometallic Chemistry 4 (1990), S. 127-131 
    Details
    ISSN: 0268-2605
    Keywords: Flame retardant ; smoke suppressant ; iron-containing organometallics ; poly(vinyl chloride) ; cable ; Limiting Oxygen Index ; smoke density ; Chemistry ; Organic Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The incorporation of a range of iron-containing organometallic compounds into a cable and wire poly(vinyl chloride) (PVC) formulation has been investigated. Limiting Oxygen Index and smoke density data were obtained across a range of formulations and the effects of the compounds on flammability and smoke generation are discussed. All the organoiron compounds markedly reduce smoke formation and some of them synergistically reduce the flammability of the polymer.

    Synthesis of a novel ferrocene derivative having flame-retardant and smoke-suppressant properties (1988)
    New York, NY [u.a.] : Wiley-Blackwell
    Applied Organometallic Chemistry 2 (1988), S. 277-280

    Keywords: Ferrocene ; chlorendic anhydride ; flame retardant ; smoke suppressant ; flexible PVC ; 1H NMR spectra ; Chemistry ; Organic Chemistry

    Topics: Chemistry and Pharmacology
    Notes: Reaction of ferrocene with chlorendic anhydride (1,4,5,6,7,7-hexachloro-5-norbornene-2,3-dicarboxylic acid anhydride) under Friedel-Crafts reaction conditions affords a new monosubstituted dervative of ferrocene which has significant flameretardant and smoke-suppressant properties when incorporated into poly(vinyl chloride) (PVC). The monocarboxylic acid from the above reaction undergoes smooth methylation with diazomethane to give the corresponding methyl ester. 1H and 13C NMR spectra of these compounds have been compared with those obtained from similar compounds, namely β-ferrocenoylpropanoic acid and its methyl ester. Distant asymmetric centres in the chlorendic anhydride substituent markedly affect the proton spectra of the ferrocene derivative.
