Mechanism of Aniline Oxidative polycondensation

摘要

The regularities of polyaniline formation, the influence of various additions, the conditions of synthesis of the main and intermediate (including hydrolysis) products on the structure of obtained materials are studied. Making use of kinetic and thermochemical methods, the mechanisms of polycondensation by N-phenyl-l,4-benzoquinonodiimine initiate the growth of macromolecules as result of the addition of anilines to electrophile quinonoimine groups of the polymer. The chemical aspects of reactions leading to formation of structural heterogenetics, branchings, breaching of effective conjugation, termination and sewing together of chains are analyzed.
