FLAMMABILITY AND SMOKE-FORMING ABILITY OF POLYMERIC MATERIALS CONTAINING FERROCENE DERIVATIVES

The influence of the concentration and chemical nature of ferrocene derivatives on heat resistance, flammability and smoke-forming ability of polymer materials based on polymers of coking has been considered. It is shown that the use of these compounds not only reduces smoke-forming ability, but also reduces the flammability of polymeric materials based on PVC and epoxy oligomers. The mechanism of action was caused by the formation of ferrocene derivatives during their decomposition highly catalytically active iron oxides inhibit the formation of benzene and smoke. It has been established that the optimum concentration of iron derivatives cyclopentanedienyl sandwiched materials for polymers on the basis of coking is 0.3–0.5 wt. %. It has been revealed that the chemical structure and content of the investigated ferrocene derivatives have almost no effect on the decomposition of epoxy resins and PVC materials at low temperatures, but they affect the coking degradation of polymers in the high temperature region at a temperature above 310 °Ñ. Thus ferrocene derivatives are more effective than ferrocene.
