Abstract:

Oxidative polymerization of benzylidenephenylenediamines produced polymers containing conjugated double bonds. Kinetic studies of the processes of oxidative polymerization of benzylidenephenylene diamines were carried out. The obtained kinetic dependencies allowed us to suggest the mechanism of oxidative polymerization of benzylidenephenylenediamines, which flows through the stage of formation of the cation radical, dimmer, tetramer, leading eventually to the formation of the polymer. In this case the limiting stadia is the formation of cation-radical, and chain growth occurs by N-C. A study of the thermal properties of the polymers showed that polybenzylidenephenylenediamines is characterized by rather high values of heat resistance. It was found that the process of destruction of most of the synthesized polymers occurs in several stages and depends on the chemical structure of the macromolecule.
