Rm. Aseeva et Ge. Zaikov, FLAMMABILITY OF MACROCYCLIC POLYMERS AND THEIR COMPLEXES WITH METALS, Die Makromolekulare Chemie. Macromolecular symposia, 74, 1993, pp. 335-338
The peculiarities of thermal degradation and the flammability of nitro
gen-containing macrocyclic polymers have been investigated. It has bee
n shown that the thermal and thermo-oxidative stability of these polym
ers depend on the structure of the macrocycle,the type of organic radi
cals 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 macrocy
clic polymers has been studied. Metals (Cu, Co, Ni) in the coordinatio
n sphere increase the thermal stability and decrease the thermo-oxidat
ive degradation of macrocyclic polymers.
