STABILIZATION AND MODIFICATION OF POLYETHYLENETEREPHTHALATE - Photochemical Reactions in Heterochain Polymers - page 122

of decay of hexaazocyclanes are in the region of T melt =300-345 0 C and T dec =327-365 0 C;
temperatures of check points of mass loss are also very high, that shows potential possibility
of introducing compounds HC-1 - HC-7 into PETP melt, as their thermal stability exceeds
temperature of PETP production and forming.
