The effect of halogen additives, containing bromine as one of the substituents (e.g. CF 2 CIBr, CF 3 Br), on the self‐ignition of polypropylene has been investigated. These compounds appear to promote self‐ignitionat low concentration and inhibit self‐ignition at high concentration when introduced into the oxidant gas. The lability of bromine is thought to influence the limiting concentration above which these additives act as inhibitors. By comparison with other systems of oxidation the authors propose an explanation an explanation in which HBr and Br' radical species are the only active entities in all cases.
