| Abstract: | The incorporation of a poly[ferrocene-1, 2 (1, 3: 1, 1′)diylmethylene] fraction with M?n=2100 as a smoke suppressant additive into both unplasticized and di(2-ethylhexyl)phthalate-plasticized, calcium carbonate-filled poly(vinyl chloride) (PVC) compositions entails appreciable reductions in smoke evolution during combustion tests relative to unmodified formulations. Best results, with smoke density reductions in the range 25-80%, are obtained at the 3% loading level, with higher additive concentrations causing no further improvements. The findings of this study may have implications on the design of other polymeric engineering materials exposed to potential fire hazards. |
