This article addresses the use of aliphatic, cycloaliphatic and aromatic petroleum resins obtained by radical (thermal and initiated) and ionic polymerization of unsaturated compounds of various fractions of liquid pyrolysis products as starting materials for modification by nitration with nitric acid and subsequent reduction with iron in the presence of hydrochloric acid. It has been established that nitration of petroleum resins leads to the appearance of nitro-, nitrate-, carbonyl and carboxyl groups in the polymer chain. Further modification of petroleum resins allows the introduction of amino groups into the composition of resins and significantly improves the performance characteristics of coatings based on the obtained resins: hardness, adhesion, and bending and impact strength
