✦ Synopsis

Abstracl--Studies have been made of the smoke-forming tendency of burning polystyrene and of the influence thereon of some established flame retardants, of a non-aromatic polymer and of a number of relatively unreactive oxides and other similar materials. The flame retardants generally increase smoke formation but decrease the rate of consumption of the polymer and, in order to separate the two effects, measurements have been made of the maximum amount of smoke generated and of the quantity of smoke formed per unit weight of polystyrene burnt. The incorporation of high-density polyethylene does not significantly reduce smoke production until a substantial proportion of the aromatic polymer has been replaced. At the relatively low levels used, most of the inert solids decrease only slowly both flammability and smoke formation but pyrogenic silica, even when present in very small concentrations, has a striking smoke-suppressant influence, the magnitude of which is directly related to its total available surface area.
