Abstract

The mechanism of interactions of NO, NO2, NO3 as well as dimers of NO2 with functional groups of organic molecules and polymers is considered. It is shown that nitrogen oxides are active initiators of radical reactions as a result of which various molecular products of nitration and stable nitrogen-containing radicals are formed. Features of the initiation mechanism determining the composition of molecular and radical products of conversions of the compounds on exposure to nitrogen oxides have been revealed.
