FLAMMABILITY OF MACROCYCLIC POLYMERS AND THEIR COMPLEXES WITH METALS

The peculiarities of thermal degradation and the flammability of nitrogen-containing macrocyclic polymers have been investigated. It has been shown that the thermal and thermo-oxidative stability of these polymers depend on the structure of the macrocycle,the type of organic radicals of the main unit and the metal nature. The effect of the type of pi-conjugated macromolecules, as well as of the planarity and symmetry of macrocycle,on thermal stability as well as flammability of macrocyclic polymers has been studied. Metals (Cu, Co, Ni) in the coordination sphere increase the thermal stability and decrease the thermo-oxidative degradation of macrocyclic polymers.
