The principles of thermochemical interaction of polymers based both on homo- and
heterophase compatibility in solid phase, and in solution are considered. The temperature and
kinetic parameters of maximum thermoreactivity of a number of carbo- and heterochain
polymers are determined. The possibilities of intermolecular interaction of
thermodynamically compatible macromolecular compounds depending on the chemical
structure of initial composition components as well as concentration and temperature-time
parameters are shown. It was established that favorable conditions for co-carbonization of
polymers are both a close coincidence of temperature intervals of their thermostability and
realization of interaction of initial components in diffusion area as well. The experimental
information received for a number of nitrogen containing polymers (polyacrylonitrile,
polyimide, polybenzimidazole, polyquinoline, chitin, chitosan etc.) shows forming of the
products of carbonization with high thermal characteristics and coke number that are different
from initial polymers. These products are perspective as catalysts for destructive treatment of
polymeric waste.
