Summary

The present knowledge of the possibilities of reducing the evolution of smoke during combustion of polymers, with particular attention devoted to unsaturated poly- ester resins, has been discussed. Several types of these resins have been pyrolyzed at temperatures in the range of 300—700°C in the form of castings and laminates rein- forced with glass fibre with the addition of nine different compounds, which affect the emission of smoke. The reduction of the mass optical density of smoke (MODS) has been observed, reaching in several cases the value of 36%, but higher values of MODS reduction, as quoted by other authors, could not be attained. The results of experiments have been presented in the form of MODS dependence on the pyrolysis temperature of resin and laminate samples, type of resin and additive.
