To synthesize resins with oxygen-containing functional groups the C9 fractions of hydrocarbon pyrolysis, heavy gasoline, and light coal tar fraction obtained from coal coking liquid products (CCLP) were used. Various types of initiators and industrial monomers were obtained using the above-mentioned non-target and/or by-products of organic raw materials processing: by the initiated oligomerization method (from C9 fractions) – petroleum polymer resins with functional groups; by radical cooligomerization (from CCLP) (with RPKV) – coumarone-indene resins with functional groups. The influence of the main factors controlling the synthesis process of resins with functional groups on their quantitative and qualitative characteristics was studied, including the process temperature, duration, and the reaction mixture composition. The structure of the synthesized resins was analyzed by IR spectroscopy, and the presence of epoxy, carboxyl, hydroxyl, and methacrylate functional groups was confirmed.
